RELEASE NOTES FOR RMAGEN
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
NOTE The user may now drag and drop RM1/ or GEO/BIN files onto a shortcut to
|
|
|
|
|
|
|
|
RMAGEN to initiate the program. The correct directory will be selected
|
|
|
|
|
|
|
|
and the user prompted as to whether a map file is to be used. Remember that a
|
|
|
|
|
|
|
|
map file is not required and will only be needed when nodal elevation data
|
|
|
|
|
|
|
|
is to be interpolated.
|
|
|
|
|
|
|
|
Version 8.4c July 2021
This update revises the treatment of output shapefiles so that both polygon and
point shapefiles can be output.
Version 8.4b May 2021
This update corrects a bug when reading cross-section files.
Version 8.4a Dec 2020
This update expands the map options for reading map files so that polygon shapefiles
that form a system outline can be processed when initially forming a network. In
addition, more shapefile options are available for network output
Version 8.4 June 2020
This update addresses two features of RMAGEN.
1. The treatment of GRD format map files has been modified so that when bed levels
are automatically interpolated from the grid defined grid location. In addition, the size
capability has been updated so that almost unlimited numbers grid cells can be input.
Finally, the display capability of this input data has been refined to build and then
display an image. For very large systems this make display faster and not subject to
a situation where a timeout occurs when drawing.
2 The mesh option which allows expansion of a 1-D line of elements to 2-D rectangular
elements has been expanded to allow the user to select how many elements there will be
across the section.
There are in addition a minor bug fix associated with map triangulation and the addition of
an option to read outline lists from a file prior to triangulation.
Version 8.3h Nov 2019
This minor update adds the 2dm (mesh) format file as potential input to or output by
RMAGEN. It also corrects a minor display bug for 1-D elements.
|
|
|
|
|
|
|
|
Version 8.3G Sept 2018
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
As a later addition a minor bug fix has corrected display of 2 node junction elements
|
|
|
|
|
|
|
|
and modified the refine process to help ensure that when control structures are refined
|
|
|
|
|
|
|
|
the initial 3 nodes that defined the upstream line are preserved. Finally refinement of
|
|
|
|
|
|
|
|
type 999 elements has been corrected so that clean operation correctly refines the adjacent
|
|
|
|
|
|
|
|
1-D element.
|
|
|
|
|
|
|
|
Input of 6 and 8 node 2dm formats is now supported.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3f November 2017.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This release includes a number of updates designed to refine operation of RMAGEN.
|
|
|
|
|
|
|
|
1 Bed elevations are now added to 1-D nodes when cross-sections are input
|
|
|
|
|
|
|
|
2 RMAGEN has been modified to allow addition of a slot in 1-D cross-sections
|
|
|
|
|
|
|
|
so that 1-D nodes will not go dry during RMA-2 simulations.
|
|
|
|
|
|
|
|
3 A 3-D view option of the mesh layout has been added. This allows a visual
|
|
|
|
|
|
|
|
display of the mesh from any angle so that errors/inconsistencies can be detected.
|
|
|
|
|
|
|
|
4 Element colours have been adjusted for clearer display when a background
|
|
|
|
|
|
|
|
image is displayed.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3e January 2017.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This release improves performance of RMAGEN in a number of areas
|
|
|
|
|
|
|
|
1 Treatment of very large systems has been modified so that display does not go
|
|
|
|
|
|
|
|
into a repeated loop when these systems are redrawn. This is achieved by
|
|
|
|
|
|
|
|
painting the output to a background file and then projecting it onto the screen.
|
|
|
|
|
|
|
|
In addition an option has been added to the RDRAW menu that switches this process
|
|
|
|
|
|
|
|
on and off. Finally the model has been modified so that a key stroke will stop
|
|
|
|
|
|
|
|
the full network painting (if it accidentally occurs) and replace it with an outline
|
|
|
|
|
|
|
|
view.
|
|
|
|
|
|
|
|
2 The process of merging networks has been reviewed and made faster and more reliable
|
|
|
|
|
|
|
|
when 1-D elements are included. Space is now left to the full width of the 1-D
|
|
|
|
|
|
|
|
elements.
|
|
|
|
|
|
|
|
3 To reflect the more frequent use of large networks the standard limits have been
|
|
|
|
|
|
|
|
increased to 200,000 nodes and 120,000 elements.
|
|
|
|
|
|
|
|
4 Formats for the GFGEN format network output option have been expanded to allow
|
|
|
|
|
|
|
|
for larger systems.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3d December 2016
|
|
|
|
|
|
|
|
This release modifies the testing to allow some tolerance for matches between coordinate
|
|
|
|
|
|
|
|
locations and map locations when assigning bed elevations using a triangulated data set.
|
|
|
|
|
|
|
|
This change helps to minimize assignment failures in this process.
|
|
|
|
|
|
|
|
A second change modifies the output of file images in jpg format to add a jpgw auxiliary
|
|
|
|
|
|
|
|
file that provides world registration of the image. In addition the manual registration
|
|
|
|
|
|
|
|
process has been modified to permit output of jpgw files.
|
|
|
|
|
|
|
|
Finally, reading of restart files written by the internal backup process has been adjusted
|
|
|
|
|
|
|
|
to add more chance of recovery after serious failures
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3c September 2016
|
|
|
|
|
|
|
|
This release expands the capabilities of the module to automatically generate triangular
|
|
|
|
|
|
|
|
grids. Each of these options requires the availability of TRIANG (developed by Sawchuck).
|
|
|
|
|
|
|
|
This package is not supplied with RMAGEN and must be separately downloaded.
|
|
|
|
|
|
|
|
Two features have been added:
|
|
|
|
|
|
|
|
(a) The ability to add mesh by defining a succession of outline points and assigning a
|
|
|
|
|
|
|
|
nominal element scale. This option is accessed from the “MESH/INPUT OUTLINE TO ADD MESH”
|
|
|
|
|
|
|
|
menu.
|
|
|
|
|
|
|
|
(b) The ability to generate a complex mesh with internal break lines from a map data.
|
|
|
|
|
|
|
|
This option requires a map file that first defines a system outline and then a series of
|
|
|
|
|
|
|
|
lines that will form the break lines.
|
|
|
|
|
|
|
|
In addition the module has been modified to add a test for zero width in cross-section data
|
|
|
|
|
|
|
|
and to correct a bug in array allocation that appeared when the number of elements exceeded
|
|
|
|
|
|
|
|
the number of nodes (a very rare occurrence). In addition RMAGEN now allows GFG and TRIANG
|
|
|
|
|
|
|
|
format files to be properly recorded in the list of mesh filenames
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3b June 2016
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This release adds a new option designed to permit input of element inflow files,
|
|
|
|
|
|
|
|
display the appropriate location and if desired reassign the locations to a different
|
|
|
|
|
|
|
|
element layout and save them to a new file. Additionally, by displaying the element
|
|
|
|
|
|
|
|
inflows either as maxima or a sum over a period, these functions are also designed
|
|
|
|
|
|
|
|
to ensure element inflows are correctly defined. Currently these options are
|
|
|
|
|
|
|
|
implemented RMA-2 and RMA-10 format files. These options are currently available
|
|
|
|
|
|
|
|
through the experimental menu and should be used with caution.
|
|
|
|
|
|
|
|
In additions two bugs have been resolved. One limited the effectiveness of interval
|
|
|
|
|
|
|
|
reordering for very large systems with high initial front widths. The other resolved
|
|
|
|
|
|
|
|
an issue arising for very large networks output as shapefiles.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3a Feb 2016
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This release adds a new option designed to permit generation of so-called
|
|
|
|
|
|
|
|
“shear stress” files that may be used in RMA-11 as an input file of bed stresses
|
|
|
|
|
|
|
|
associated with wave activity. It is designed to interpolate onto the finite
|
|
|
|
|
|
|
|
element network a wave related stress data available on any x-y basis or as a
|
|
|
|
|
|
|
|
ESRI grid file (that is in one of the available map file formats). This option
|
|
|
|
|
|
|
|
is entered through the experimental menu option. For further information
|
|
|
|
|
|
|
|
see section 5.19.
|
|
|
|
|
|
|
|
A second update allows background files in PNG or JPG format with associated world
|
|
|
|
|
|
|
|
files (PNGW or JPGW) to be directly imported in RMAGEN.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.3 Jan 2016
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This is a new release that has several new capabilities
|
|
|
|
|
|
|
|
(a) A file menu option that allows multiple map files of varying types to be loaded
|
|
|
|
|
|
|
|
into the system and combined.
|
|
|
|
|
|
|
|
(b) A file menu option that allows networks to be saved in shapefile format for input
|
|
|
|
|
|
|
|
directly into GIS systems. Networks can be saved in complex polygon form (containing bed
|
|
|
|
|
|
|
|
elevations at nodes and element type numbers for each polygon), point form (containing bed
|
|
|
|
|
|
|
|
elevations) and conventional polygon form (containing the element and type numbers).
|
|
|
|
|
|
|
|
(c) An option on map input that allows map data to be loaded directly from point
|
|
|
|
|
|
|
|
shapefiles.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
Corrects some issues with the automatic generation of type 999 elements that connect 1-D elements
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
incorrectly applied when it is copied to a file or the clipboard.
|
|
|
|
|
|
|
|

|
Version 8.2I May 2015
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Revises the structure of the menu line to allow an experimental option where
|
|
|
|
|
|
|
|
new and only partly tested options are placed. These are options that have
|
|
|
|
|
|
|
|
limitations and are not fully documented. They should be used only after
|
|
|
|
|
|
|
|
consultation. Four options are currently in this state. See section 5.19
|
|
|
|
|

These releases update a number of features of RMAGEN and add a fairly specialized
|
|
|
|
|
|
|
|
option for creation of weir/levee data
|
|
|
|
|
|
|
|
(a) Removes bugs associated with deletion and addition of cclines and display

Version 8.2B Sept 2014
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This release adds a number of updates to RMAGEN.
|
|
|
|
|
|
|
|
(a) Improves the screen information during the GBLOCK operation of RMAGEN
|
|
|
|
|
|
|
|
(b) Adds an option to create a block of 2-D elements from a line of 1-D elements
|
|
|
|
|
|
|
|
(c) Adds an option to create a block of 2-D elements from 2 roughly parallel map lines
|
|
|
|
|
|
|
|
(d) Adds an option to select and then move a group of nodes
|
|
|
|
|
|
|
|
(e) Adds extra decimal precision to the make ap from nodes menu option
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.2A July 2014
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This update adds to the mesh menu an option allows all overlapping nodes (within
|
|
|
|
|
|
|
|
an input tolerance) to be joined. This option may be used to correct situations
|
|
|
|
|
|
|
|
where nodes accidentally overlap or for cases where meshes with common nodes are merged.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.2 June 2014
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This update adds the ability to process jpg files as background images. In addition
|
|
|
|
|
|
|
|
further tests have been added to RMAGEN to make merging of meshes more reliable. A
|
|
|
|
|
|
|
|
check of correct nodal connections have also been added. An option has been added
|
|
|
|
|
|
|
|
to allow more operations when element types are selected.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1N August 2013
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This update clears some of the difficulty of operation when using add and merge options
|
|
|
|
|
|
|
|
on two meshes. In addition RMAGEN has been modified to cause the network to be
|
|
|
|
|
|
|
|
displayed in outline mode when there are more than 100,000 nodes in a network. This is
|
|
|
|
|
|
|
|
designed to speed initial operations.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1M July 2013
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This update adds an additional option to the mesh menu to allow deleting of all
|
|
|
|
|
|
|
|
elements with a particular type number.
|
|
|
|
|
|
|
|
|
|
|

|
|
Version 8.1L February 2013
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
An additional option for mesh transformation has been added
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Option 3 transforms the coordinate system by a arc rotation (an input number in radians)
|
|
|
|
|
|
|
|
about input defined coordinates.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1K January 2013
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This minor update refines the precision output and display of bed elevations so that
|
|
|
|
|
|
|
|
when numerically small numbers are used extra decimal places are shown/saved.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1 I and J December 2012
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This update adds an additional option the mesh menu that will provide a framework for
|
|
|
|
|
|
|
|
future operations on the entire mesh. They are mostly aimed at test use of the models.
|
|
|
|
|
|
|
|
Currently two options are implemented.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Option 1 moves the geometry to a new coordinate system both as a shift and as a scale,
|
|
|
|
|
|
|
|
bed elevations may be similarly scaled.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Option 2 transforms the coordinate system into a circular curve.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Full details of the required inputs and methods used are provided in the section describing
|
|
|
|
|
|
|
|
mesh options.

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This minor update refines the process for treatment of very large systems that
|
|
|
|
|
|
|
|
are two large for the initial dimensions. A display is added that allows the user
|
|
|
|
|
|
|
|
to expand the limits to provide working space when loading very large systems.

|
|
|
|
|
|
This minor update adds a series of options that allow reading, creation,
|
|
|
|
|
|
|
|
display and saving of group numbers for input to RMA-2 and/or RMA-11.
|

Version 8.1C AND D July 2011
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
These minor updates correct some inconsistencies and adds two options
|
|
|
|
|
|
|
|
1 In the menu "Mesh" an option has been added that permits
|
|
|
|
|
|
|
|
movement/rescaling of the coordinate system.
|
|
|
|
|
|
|
|
2 In the "Select/Element" menu an option has been added to
|
|
|
|
|
|
|
|
allow the user to select elements by element type.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1B March 2011
|
|
|
|
|
|
|
|
This minor update designed allows the user to directly select a file name
|
|
|
|
|
|
|
|
when creating map points from the menu option.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1A January 2011
|
|
|
|
|
|
|
|
This minor update
|
|
|
|
|
|
|
|
(1) expands the input formats so that free field (comma delimited)
|
|
|
|
|
|
|
|
element connections can be processed.
|
|
|
|
|
|
|
|
(2) revises the 3-D view so that as the view is zoomed in or out the
|
|
|
|
|
|
|
|
vertical scale is adjusted to maintain the aspect ratio .
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 8.1 Sept 2010
|
|
|
|
|
|
|
|
This is an update designed to generate improved network quality.
|
|
|
|
|
|
|
|
(1) RMAGEN now offers expanded network checking capability.
|
|
|
|
|
|
|
|
The purpose is to allow two-dimensional mesh builders to assess the
|
|
|
|
|
|
|
|
variability of bed levels across elements and for one-dimensional
|
|
|
|
|
|
|
|
elements to assess variability of bed levels and cross-sections.
|
|
|
|
|
|
|
|
The Check toolbar function has been expanded to allow two types of
|
|
|
|
|
|
|
|
network testing. One computes absolute values of bed level/cross-section
|
|
|
|
|
|
|
|
change and the other computes a normalized value of depth
|
|
|
|
|
|
|
|
change/cross-section. Once computed these values are displayed as
|
|
|
|
|
|
|
|
equivalent contours on an element by element basis. An option on the
|
|
|
|
|
|
|
|
SELECT menu item now allows the user to select the elements with higher
|
|
|
|
|
|
|
|
values of the differences (the user inputs the fraction at the time
|
|
|
|
|
|
|
|
of access) and then refine these elements.
|
|
|
|
|
|
|
|
(2) A second addition to the SELECT menu item now allows the user
|
|
|
|
|
|
|
|
to find pairs of adjacent triangular elements that form a quadrilateral
|
|
|
|
|
|
|
|
that has interior angles greater than 90 deg so that the original diagonal
|
|
|
|
|
|
|
|
can be reversed and lead to an improved layout (that is, smaller interior
|
|
|
|
|
|
|
|
angles). The user can select how many pairs are to be reversed in any
|
|
|
|
|
|
|
|
single step. This option is particularly useful when element refinement
|
|
|
|
|
|
|
|
operations have been undertaken.
|
|
|
|
|
|
|
|
|

Version 8.0D June 2010
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This version:
|
|
|
|
|
|
|
|
(1) Adds an error message when background images are too large
|
|
|
|
|
|
|
|
to display.
|
|
|
|
|
|
|
|
(2) Increase limits for formation of 1-D and type 999 elements from
|
|
|
|
|
|
|
|
the "MESH" menu.
|
|
|
|
|
|
|
|
Add a registration capability when background images are slightly in
|
|
|
|
|
|
|
|
error.
|
|
|

Version 8.0A, B and C April-May 2010
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
These are minor releases correcting a few bugs that arose from the switch to
|
|
|
|
|
|
|
|
Intel Visual FORTRAN.
|
|
|
|
|
|
|
|
Initialization of dialogs is improved.
|
|
|
|
|
|
|
|
A bug in allocation of cross-section weighting when there are missing sections
|
|
|
|
|
|
|
|
has been fixed.
|
|
|
|
|
|
|
|
Some error messages have been improved.
|
|
|
|
|

|
|
|
Version 8.0 January 2010
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This is a new release that adds a number of features to RMAGEN. The principal
|
|
|
|
|
|
|
|
technical update has been a switch to the Intel Visual FORTRAN compiler and the
|
|
|
|
|
|
|
|
associated Winteracter library and allocatable arrays have been introduced.
|
|
|
|
|
|
|
|
RMAGEN has now been revised to permit 3-D views of the network with or without
|
|
|
|
|
|
|
|
contours once it has been created. The contour option has been modified so that
|
|
|
|
|
|
|
|
the element layout may be superimposed on top of the contours. This can clarify
|
|
|
|
|
|
|
|
the perspectives of a 3-D view. Specifically the following additional menu items
|
|
|
|
|
|
|
|
and buttons have been added.
|
|
|
|
|
|
|
|
1 In the VIEW menu, the “View in 3-D” item initiates the 3-D view capability
|
|
|
|
|
|
|
|
and presents a dialog box that allows the user to set view angles and scale and
|
|
|
|
|
|
|
|
origin values.
|
|
|
|
|
|
|
|
2 In the VIEW menu, the “Set View Angle” allows the user to reset or adjust
|
|
|
|
|
|
|
|
the viewing angles.
|
|
|
|
|
|
|
|
3 A new button has been added that when clicked allows the user to rotate
|
|
|
|
|
|
|
|
the viewing point in the horizontal plane (by clicking and dragging the mouse
|
|
|
|
|
|
|
|
horizontally on the lower section of the screen) and rotate the viewing point in
|
|
|
|
|
|
|
|
the vertical plane (by clicking and dragging the mouse vertically on the right
|
|
|
|
|
|
|
|
section of the screen).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The user now has control over the size limits. In the FILE menu an option has
|
|
|
|
|
|
|
|
been added that slows the user to “reset” the limits on the maximum nodes, maximum
|
|
|
|
|
|
|
|
elements and max map points before files are input. Note that once the maximum
|
|
|
|
|
|
|
|
number of nodes and elements have been set, they may not be adjusted. However,
|
|
|
|
|
|
|
|
if an oversized map file is being loaded, the user is invited to reset this limit.
|
|
|
|
|
|
|
|
If a GEO file is loaded that is too large (without the reset option having been
|
|
|
|
|
|
|
|
used) the “reset” dialog is automatically displayed so that the user can set
|
|
|
|
|
|
|
|
acceptable limits.
|
|
|
|
|
|
|
|
|
|
|
|
|

Version 7.4a JUNE 2009
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This update corrects a bug introduced in an earlier update that made merging and
|
|
|
|
|
|
|
|
adding of networks unreliable.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.4 JULY 2008
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This is an update designed to add additional input/output capabilities.
|
|
|
|
|
|
|
|
The model is now capable of inputting files generated by TRIANG and outputting
|
|
|
|
|
|
|
|
files for use by TRIANG. For information on TRIANG which is a free triangular
|
|
|
|
|
|
|
|
mesh generated program developed by Jonathan R Shewchuk
|
|
|
|
|
|
|
|
(see web site http://www.cs.cmu.edu/~quake/triangle.html.
|
|
|
|
|
|
|
|
A second addition has been the option to outline the user to generate a file of points
|
|
|
|
|
|
|
|
that can be used as a mesh outline. This list can be generated in *.poly form that can
|
|
|
|
|
|
|
|
be used as input to TRIANGLE or in *.dat for adaptation as an outline in a "map" file.
|
|
|
|
|
|
|
|
This option is accessed through the MESH menu.
|
|
|
|
|
|
|
|
Finally, a few changes have been made to make RMAGEN more user friendly.
|
|
|
|
|
|
|
|
• When interpolating bed elevations the user does not have to return to the “single”
|
|
|
|
|
|
|
|
box.
|
|
|
|
|
|
|
|
• When the user selects a group of nodes and then desires to set elevation a number
|
|
|
|
|
|
|
|
of options are now offered.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
Version 7.3H JULY 2007
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This version expands the CCLINE menu to permit continuity lines to be updated
|
|
|
|
|
|
|
|
(via a menu choice) when elements have beebn refined in the area of the CCLINES.
|
|
|
|
|
|
|
|
A second enhancement insures that 2-d control structures are preserved (in a
|
|
|
|
|
|
|
|
directional sense) when split into two elements during a refinement process.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.3G OCTOBER 2006
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
A series of new options have been added,
|
|
|
|
|
|
|
|
(a) the ability to split a line of nodes (or a single node) so that a gap
|
|
|
|
|
|
|
|
is created. This gap can optionally be filled with elements.
|
|
|
|
|
|
|
|
This offers an easy method for adding weir elements or adding extra
|
|
|
|
|
|
|
|
resolution along a line such as a river or navigation channel.
|
|
|
|
|
|
|
|
The “split a line” option found in the MESH menu allows the user split
|
|
|
|
|
|
|
|
a line of nodes. It is must be used with mid-side nodes deleted.
|
|
|
|
|
|
|
|
On entry the user is presented with the screen normally used for
|
|
|
|
|
|
|
|
defining CClines. Clicking a series of nodes creates a line which is
|
|
|
|
|
|
|
|
finalized with the CONNECT button. A dialog box then offers the user
|
|
|
|
|
|
|
|
the choice of how far apart to split the nodes and whether or not to
|
|
|
|
|
|
|
|
add elements into the gap.
|
|
|
|
|
|
|
|
Note that if a single node is selected the user must define the
|
|
|
|
|
|
|
|
directions of the split. For the case of points on a line the
|
|
|
|
|
|
|
|
direction is computed automatically.
|
|
|
|
|
|
|
|
(b) the ability to generate a line of one-dimensional elements and/or type 999
|
|
|
|
|
|
|
|
elements that allow lateral transition from two-dimensional elements.
|
|
|
|
|
|
|
|
The "form a line of 1-D elements" option may be found in the MESH menu.
|
|
|
|
|
|
|
|
It offers the user the option of either creating nodes and then forming
|
|
|
|
|
|
|
|
elements or clicking on a line of existing nodes to form the elements.
|
|
|
|
|
|
|
|
The user can optionally assign the same properties to each node or enter
|
|
|
|
|
|
|
|
properties through a dialog box. The "form type 999 elements" also in
|
|
|
|
|
|
|
|
the MESH menu goes one step further It allows the user either to create
|
|
|
|
|
|
|
|
1-D elements as above or input a line of 1-D nodes. Then RMAGEN
|
|
|
|
|
|
|
|
automatically creates type 999 elements that abut the 1-D line on either
|
|
|
|
|
|
|
|
side.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
There has been a review of treatment of layer data in RMAGEN, as a result it
|
|
|
|
|
|
|
|
is now possible to save ASCII files of layer data for direct addition to
|
|
|
|
|
|
|
|
RMA-10 input files.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
Version 7.3f
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
updates the DEMo option to make it consistent with the latest
|
|
|
|
|
|
|
|
options for reordering and simplifies initial operation.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.3e
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
restores the ability of RMAGEN to display and generate layer data.
|
|
|
|
|
|
|
|
An option in the dialog displayed when the DISP toolbar is clicked allows the
|
|
|
|
|
|
|
|
user to select display of the number of layers on a node by node basis. Only
|
|
|
|
|
|
|
|
nodes that do not have the default number of layers (9999) are shown. The layer
|
|
|
|
|
|
|
|
option is selected in the "ELEV" box menu the user may choose the number of layers
|
|
|
|
|
|
|
|
and the data values needed for the LD2 or LD3 option. A similar set of options
|
|
|
|
|
|
|
|
now appear when nodes are selected from the “SELECT” menu.
|
|
|
|
|
|
|
|
This version also permits the user to select a REORDER/ALL option from the
|
|
|
|
|
|
|
|
dropdown menus. This executes the reordering processor using as starting seeds
|
|
|
|
|
|
|
|
each network element. PLEASE NOTE THAT FOR LARGE SYSTEMS THIS CAN BE VERY TIME
|
|
|
|
|
|
|
|
CONSUMING AND IS ONLY RECOMMENDED WHEN OTHER REORDERING OPTIONS HAVE BEEN FULLY
|
|
|
|
|
|
|
|
EXPLORED
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.3d
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds the ability to input and save SMS format “bin” files and fixes a
|
|
|
|
|
|
|
|
bug when saving GFGEN files.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.3c
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds the ability to extract parts of a mesh and save them to a file.
|
|
|
|
|
|
|
|
This option is designed to be used when manipulating large meshes, so that the
|
|
|
|
|
|
|
|
user is better able to debug a network by first simplifying then adding
|
|
|
|
|
|
|
|
detail on a block by block basis.See section 1.10 of the documentation.
|
|
|
|
|
|
|
|
A separate addition to the "CSECT" menu permits display of cross-sections loaded
|
|
|
|
|
|
|
|
from the cross-section data file, see section 1.7 of the documentation.
|
|
|
|
|
|

|
|
Version 7.3b
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds an initial capability designed to permit automatic construction
|
|
|
|
|
|
|
|
of networks based on the bathymetry. Two new options have been added to the MESH
|
|
|
|
|
|
|
|
dropdown menus. One enables construction of contour lines in "MAP" file format
|
|
|
|
|
|
|
|
from existing nodal point values. The second allows mesh generation based on these
|
|
|
|
|
|
|
|
contour lines. See section x.x of the documentation for further information on these
|
|
|
|
|
|

|
options. A second addition is addional options for display of cross-section data
|
|
|
|
|
|
|
|
on 1-D network views.
|
|
|
|
|
|

Version 7.3a
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds additional capabilities to RMAGEN that allow the user to
|
|
|
|
|
|
|
|
input, display, manipulate and save cross-section files that are to be used
|
|
|
|
|
|
|
|
in RMA-2. The FILE, CSECT and RDRAW menu items have been updated. The
|
|
|
|
|
|
|
|
FILE menu now allows input and saving of cross-section data files. The
|
|
|
|
|
|
|
|
CSECT option now has a sub-menu item (COMPUTE WEIGHTING) that permits
|
|
|
|
|
|
|
|
computation of weighting factors from data in the cross-section file, see
|
|
|
|
|
|
|
|
section 1.7 of the documentation.
|
|
|
|
|
|
|
|
The RDRAW/DRAW OPTIONS sub-menu now allows the user to select display of
|
|
|
|
|
|
|
|
cross-section locations and the weighting functions for nodes.
|
|
|
|
|
|
|
|
A function update changes the display to a dialog when input of floating point and
|
|
|
|
|
|
|
|
integer numbers is required.
|
|
|
|
|
|
|
|
A change has been made to the UNDO menu item so that users can now undo refine
|
|
|
|
|
|
|
|
operations and element selections using separate sub-menus.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.3
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
introduces a series of updates associated with manipulation of meshes.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
1 The file menu now permits the user to load additional mesh files, so that more
|
|
|
|
|
|
|
|
than one mesh may be worked on when using RMAGEN.
|
|
|
|
|
|
|
|
2 A new menu item "Mesh" has been introduced. The user may select which mesh
|
|
|
|
|
|
|
|
to activate using a sub menu from the item.
|
|
|
|
|
|
|
|
3 The "Add mesh to existing" sub-menu may be used to add to meshes together without
|
|
|
|
|
|
|
|
any regard to overlap.
|
|
|
|
|
|
|
|
4 The "merge mesh to existing" sub menu allows a mesh to be added to the existing with
|
|
|
|
|
|
|
|
the condition that where elements overlap, elements are deleted from the mesh that is added.
|
|
|
|
|
|
|
|
5 The "Generate triangular block" sub-menu allows the creation of a triangular block of
|
|
|
|
|
|
|
|
elements with different numbers of elements along each side.
|
|
|
|
|
|
|
|
6 The "Generate quadrilateral block" sub-menu allows the creation of a quadrilateral block
|
|
|
|
|
|
|
|
of elements with different numbers of elements along each side.
|
|
|
|
|
|
|
|
7 The "Nodes" sub-menu under the "Select" has been expanded to allow the user to select
|
|
|
|
|
|
|
|
nodes either from a polygon, as all nodes or as all unused nodes.
|
|
|
|
|
|
|
|
8 A new form triangles option has been added when a group of nodes has been selected using
|
|
|
|
|
|
|
|
the "Select" option.
|
|
|
|
|
|
|
|
9 A new simplify option has been added when a group of elements has been selected under
|
|
|
|
|
|
|
|
the "Select" menu. The user may use this option to reduce element density.
|
|
|
|
|
|
|
|
10 The create data option has been moved from its own main menu item to a sub-menu of
|
|
|
|
|
|
|
|
the "Map" menu.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.2
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
is an update designed to add three further map related options and
|
|
|
|
|
|
|
|
a number of other menu options have been added ot changed.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The "triangulate map data" option allows automatic triangulation of map data
|
|
|
|
|
|
|
|
using Delaunay triangularization. A set of element connections are developed
|
|
|
|
|
|
|
|
in this process so that they may be used as part of the new nodal interpolation
|
|
|
|
|
|
|
|
option discussed below. NOTE that this option can take considerable computing
|
|
|
|
|
|
|
|
resources if there are many map data points and that about twice as many
|
|
|
|
|
|
|
|
elements as map data points are created. To reduce resouce demand an additional
|
|
|
|
|
|
|
|
dialog has been created that allows the user to skip some data points or only
|
|
|
|
|
|
|
|
process points that are an input spacing from other points.
|
|
|
|
|
|
|
|
The "Switch to show Map Data" option allows the user to display a triangulated
|
|
|
|
|
|
|
|
map file as if it were an RM1 file. At that point the triangulated map file
|
|
|
|
|
|
|
|
can be operated on in the same way as any network file. In particular elements
|
|
|
|
|
|
|
|
and nodes can be deleted so that the triangulated map file can be cleaned up
|
|
|
|
|
|
|
|
to better represent the system.
|
|
|
|
|
|
|
|
The "Switch to show RM1 Data" option allows the user to revert back to the RM1
|
|
|
|
|
|
|
|
file.
|
|
|
|
|
|
|
|
The user may now save the triangulate map data when saving map information
|
|
|
|
|
|
|
|
in binary format.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Users may now load map files in RM1 format, so that externally triangulated
|
|
|
|
|
|
|
|
networks may be read in. At present, the loading process deletes all mid-side
|
|
|
|
|
|
|
|
nodes and assumes only a triangular representation of the system.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Within the NODES/ELEV menu for interpolation of bed alevations the user is now
|
|
|
|
|
|
|
|
prompted to use either a triangulated data set or use the original RMAGEN
|
|
|
|
|
|
|
|
interpolation.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
An addiitonal option has been added to the file menu that permits the user to
|
|
|
|
|
|
|
|
save binary geometry files with headers (so that they can be used on UNIX or
|
|
|
|
|
|
|
|
LINUX systems). The file format may be slected as either "big-endian" or
|
|
|
|
|
|
|
|
"little-endian" as required by the alternate system.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.1
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
is an update designed to add two new menu options, (editing
|
|
|
|
|
|
|
|
of nodes or elements and an additional map file making capability) and
|
|
|
|
|
|
|
|
to correct two bugs that have been detected. A further addition allows
|
|
|
|
|
|
|
|
nodal connections to user 6 column formats (this is needed when element
|
|
|
|
|
|
|
|
numbers exceed 99999).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The Edit menu allows ASCII editing of nodal coordinates and element
|
|
|
|
|
|
|
|
connections. See section (1.16)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The new map-making facility allows the user to read in a network (in
|
|
|
|
|
|
|
|
the usual finite element RM1, GFG or GEO format) and output an interpolated
|
|
|
|
|
|
|
|
file over a uniformly spaced grid (with the spacing set by the user).
|
|
|
|
|
|
|
|
Thus the user who has a triangulated set of data from another source
|
|
|
|
|
|
|
|
can automatically created a high-resolution file. *See section ( 1.17)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Dimension limits on a large capacity RMAGEN have now been set to allow
|
|
|
|
|
|
|
|
up to 200,000 elements and 400,000 nodes and a 3000 by 3000 output grid.
|
|
|
|
|
|
|
|
The standard limits have now been set to 50,000 elements 100,000 nodes
|
|
|
|
|
|
|
|
and a 1000 by 1000 grid. For smaller computers, the medium limits are
|
|
|
|
|
|
|
|
set to 20,000 elements, 50,000 nodes and a 300 by 300 grid.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
NOTE that the parameter NTEMPIN on line B of the data has an expanded
|
|
|
|
|
|
|
|
set of values. See input format instructions.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The corrected errors are as follows:
|
|
|
|
|
|
|
|
(a) Double precision coordinates were not always correctly written
|
|
|
|
|
|
|
|
to RM1 files.
|
|
|
|
|
|
|
|
(b) Some steps when setting element types occasionally caused the
|
|
|
|
|
|
|
|
elements to be deleted.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 7.0
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
represents a major revision that has been designed to update the
|
|
|
|
|
|
|
|
file handling to accommodate revisions to RMA-2, RMA-10 and RMA-11
|
|
|
|
|
|
|
|
that allow for double precision storage of coordinates and larger
|
|
|
|
|
|
|
|
integers for node numbers. RMAGEN has been modified to allow input
|
|
|
|
|
|
|
|
of geometry files either from old format GEO or RM1 files or from a
|
|
|
|
|
|
|
|
newly developed formats output by version 7.0 of RMAGEN..
|
|
|
|
|
|
|
|
The “new” format RM1 file allows 20 columns for the x and y coordinates
|
|
|
|
|
|
|
|
and is referred to in RMAGEN as the “long format”. The “new” format GEO
|
|
|
|
|
|
|
|
file begins with a 1000 character header that starts with the characters “RMAGEN”
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
In addition, RMAGEN is now able to read a basic GFGEN format input file
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The fonts and general readability of RMAGEN text display has also been improved.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
On entry to the “Open” menu the model now first prompts for the network
|
|
|
|
|
|
|
|
file and then the map file.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
In addition to RM1 files the user can now open and save ascii network files generated
|
|
|
|
|
|
|
|
by SMS. In RMAGEN they are given and use the suffix "GFG" thus they should be renamed
|
|
|
|
|
|
|
|
as "GEO" to or from use in SMS. Similarly, the user may save "BIN" format binary geometry
|
|
|
|
|
|
|
|
files for use with SMS
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Bed elevations are now displayed with decimal points.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
A number of toolbar options have been implemented for easier zooming, and panning,
|
|
|
|
|
|
|
|
and filling deleting of mid-side nodes.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 6.4
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds
|
|
|
|
|
|
|
|
(a) additional data input for sloping beds in one-dimensional elements,
|
|
|
|
|
|
|
|
(b) permits the user to display data values as colored points as an
|
|
|
|
|
|
|
|
alternative to numbers and
|
|
|
|
|
|
|
|
(c) add the x and y location to a new status bar at the bottom of the active window.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 6.3
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds
|
|
|
|
|
|
|
|
a new feature to RMAGEN, namely, the ability to lock/unlock nodal
|
|
|
|
|
|
|
|
elevation values. The lock/unlock options can be accessed from the
|
|
|
|
|
|
|
|
node/elev menu or after “selecting/nodes” from the dropdown menu.
|
|
|
|
|
|
|
|
This feature allows the user to manually set nodal elevations and
|
|
|
|
|
|
|
|
then allow the interpolation routine to pick up values for other nodes.
|
|
|
|
|
|
|
|
This option is accessed node/elev box menu. This version also allows
|
|
|
|
|
|
|
|
the user to load a replacement map file during processing and save the
|
|
|
|
|
|
|
|
lock/unlock information on the rm1 and geo files.
|
|
|
|
|
|
|
|
Finally the geo file has now been modified to store reordering data so
|
|
|
|
|
|
|
|
that this information is available to the user when loading the geo
|
|
|
|
|
|
|
|
file for processing.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 6.2
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds
|
|
|
|
|
|
|
|
the capability to register corners of a loaded image using known locations
|
|
|
|
|
|
|
|
of points within the image. This option is accessed from the
|
|
|
|
|
|
|
|
Rdraw/Background/Register drop down menu. This version also adds
|
|
|
|
|
|
|
|
additional information when reordering stops because of a poorly
|
|
|
|
|
|
|
|
constructed network.
|
|
|
|
|
|
|
|
An additional change in revision (a) allows the user to delete all
|
|
|
|
|
|
|
|
continuity lines by selecting a zero continuity line number when deleting.
|
|
|
|
|
|
|
|
|
|
|
|
|

|
Rev 3 of Version 6.1
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
is a modification designed to clarify the limitations of
|
|
|
|
|
|
|
|
RMAGEN when copying and printing files that contain background images.
|
|
|
|
|
|
|
|
The limitations are those imposed by the graphics library and will be
|
|
|
|
|
|
|
|
removed as soon as possible.
|
|
|
|
|
|
|
|
Copy file limitations.
|
|
|
|
|
|
|
|
1 Networks only can be copied in any of the available formats.
|
|
|
|
|
|
|
|
2 Networks with background images can only be saved in “emf” format
|
|
|
|
|
|
|
|
and the background image must have been input in a vector format,
|
|
|
|
|
|
|
|
i.e. a non bitmap format.
|
|
|
|
|
|
|
|
3 At present copied image files may revert to the full size of the
|
|
|
|
|
|
|
|
image even if there has been a zoom operation. This limitation
|
|
|
|
|
|
|
|
does not apply to clipboard or printed images. The extent of
|
|
|
|
|
|
|
|
the image displayed depends on Windows application. In general
|
|
|
|
|
|
|
|
this means that size of this saved image may be very large.
|
|
|
|
|
|
|
|
If the user wishes to copy and save images of a small section of
|
|
|
|
|
|
|
|
the network, it is recommended that an external graphics or GIS
|
|
|
|
|
|
|
|
program be used to construct a wmf file that covers the area of interest.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 6.1
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
adds a series of new capabilities designed to enhance usage:
|
|
|
|
|
|
|
|
1 The capability of displaying background files. These files may
|
|
|
|
|
|
|
|
be in a variety of formats, either bitmap format (bmp, pcx or png)
|
|
|
|
|
|
|
|
or vector format (wmf, cgm, or pic). For further details see a
|
|
|
|
|
|
|
|
new section that describes necessary formats for the background file.
|
|
|
|
|
|
|
|
2 The addition of an “undo” menu option that may be used following
|
|
|
|
|
|
|
|
generation of a block of elements to delete the entire new block
|
|
|
|
|
|
|
|
or following refinement to remove the last refinement step, even
|
|
|
|
|
|
|
|
after the “clean” operation
|
|
|
|
|
|
|
|
3 During display some of the plotted numbers have been reduced in
|
|
|
|
|
|
|
|
size to reduce congestion on the screen.
|
|
|
|
|
|
|
|
4 The screen display may now be written to the clipboard.
|
|
|
|
|
|
|
|
5 The “makemap” option has now been modified to output the map file
|
|
|
|
|
|
|
|
in a type 2 format.
|
|
|
|
|
|
|
|
6 This manual has been expanded by the addition of two appendices.
|
|
|
|
|
|
|
|
Appendix A lists the formats for the RM1 file and Appendix B gives
|
|
|
|
|
|
|
|
a series steps to guide users through the use of RMAGEN
|
|
|
|

Version 6.0
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
reflects a significant change to the treatment of continuity lines.
|
|
|
|
|
|
|
|
In this version they may be:
|
|
|
|
|
|
|
|
1. Displayed using the redraw menu. Note that this option replaces
|
|
|
|
|
|
|
|
the “grid” option that is now only available from the dropdown redraw menu.
|
|
|
|
|
|
|
|
2. Assigned a number and re-entered or deleted.
|
|
|
|
|
|
|
|
3. Saved on the binary geometry file.
|
|
|
|
|
|
|
|
A further change allows the user to construct the reordering list and
|
|
|
|
|
|
|
|
then “save” it instead of predefining the list number.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 5.4 reflects the continuing expansion of module operation.
|
|
|
|
|
|
|
|
1 The select/node option of the main menu has been enhanced to permit
|
|
|
|
|
|
|
|
the user to define a given number of 3-D layers for those nodes.
|
|
|
|
|
|
|
|
If not previously defined the user will be prompted for a file name
|
|
|
|
|
|
|
|
where this 3-D data will stored.
|
|
|
|
|
|
|
|
2 The “threed” option of the node/elev menu has been rewritten to
|
|
|
|
|
|
|
|
store values to a file.
|
|
|
|
|
|
|
|
3 Additions have been made to the ordering menu options to permit the
|
|
|
|
|
|
|
|
user to compact node and element numbers to eliminate missing numbers.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 5 has been compiled with version 4.5 of the Lahey compiler and has been
|
|
|
|
|
|
|
|
adapted to run under WINTERACTER. This offers the user a more Windows
|
|
|
|
|
|
|
|
like feel to operation of the module. Several important changes apply:
|
|
|
|
|
|
|
|
1. File opening and saving is now prompted through Windows boxes.
|
|
|
|
|
|
|
|
2. The main menu is always available at the top of the window and switching between menus may be accomplished by pointing at the appropriate identifier.
|
|
|
|
|
|
|
|
3. A number of new features are now available from drop down menus
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 4.2 revises the algorithm for computation of bottom elevations from MAP
|
|
|
|
|
|
|
|
data and shifts a number of the I/O functions to the graphics window.
|
|
|
|
|
|
|
|
An option has also been added for "Move Node" and "Refine" operations
|
|
|
|
|
|
|
|
that allows the user to reset bottom elevations to –9999 for nodes that
|
|
|
|
|
|
|
|
are moved or created during refinement. Version 4.1 allows the user to
|
|
|
|
|
|
|
|
generate continuity lines for direct input into data files of other RMA models.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Version 3.3(a) permits the user to optionally save a record of all mouse and
|
|
|
|
|
|
|
|
keystroke operations and to later play these back. These feature can
|
|
|
|
|
|
|
|
be used for debugging and producing demonstrations of model use. For
|
|
|
|
|
|
|
|
instructions on the use of this option see the file handling section
|
|
|
|
|
|
|
|
below. For information on the status see the "READ.ME" file accompanying
