|
|
random waves and random loads. WAFO is freely redistributable software, see WAFO

WAFO consists of several subpackages and classes with short descriptions given
|
||
|
|
below.
|
||
|
|
|
||
|
|
Classes:
|
||
|
|
TimeSeries - Data analysis of time series. Example: extraction of
|
||
|
|
turning points, estimation of spectrum and covariance function.
|
||
|
|
Estimation transformation used in transformed Gaussian model.
|
||
|
|
CovData - Computation of spectral functions, linear
|
||
|
|
and non-linear time series simulation.
|
||
|
|
SpecData - Computation of spectral moments and covariance functions, linear
|
||
|
|
and non-linear time series simulation.
|
||
|
|
Ex: common spectra implemented, directional spectra,
|
||
|
|
bandwidth measures, exact distributions for wave characteristics.
|
||
|
|
|
||
|
|
CyclePairs - Cycle counting, discretization, and crossings, calculation of
|
||
|
|
damage. Simulation of discrete Markov chains, switching Markov
|
||
|
|
chains, harmonic oscillator. Ex: Rainflow cycles and matrix,
|
||
|
|
discretization of loads. Damage of a rainflow count or
|
||
|
|
matrix, damage matrix, S-N plot.

||
|
|
STATS - Statistical tools and extreme-value distributions.

|
|
Ex: generation of random numbers, estimation of parameters,
|
||
|
|
