WAFO. Wave Analysis for Fatigue and Oceanography |
WAFO is a toolbox of Matlab routines for statistical analysis and simulation of random waves and random loads. The routines are collected in subdirectories according to application. Tools are provided for analysis of measured data with routines for estimation of parameters in statistical distributions, estimation of spectra, plotting in probability papers, etc.
An important part of WAFO are routines for calculation of theoretical distributions of characteristic wave parameters from observed or theoretical power spectra of the sea. Another part is related to statistical analysis of fatigue. The theoretical density of rainflow cycles can be computed from parameters of random loads. Further, a collection of routines is included for modelling of switching loads (hidden Markov models). A special part of WAFO contains general statistical tools.
A new philosophy concerning documentation is presented. The toolbox contains scripts for generation of plots in recent publications and scripts for comparison with results in the literature. Data sets from measurements of the sea surface are included.
WAFO is developed for use with Matlab version 5.x/6.x. Some routines call programs written in Fortran. Versions for PC/Windows and Unix environments are available.
WAFO replaces the two toolboxes Wave Analysis Toolbox (WAT) and Fatigue Analysis Toolbox (FAT). The development of numerical methods for calculating distributions of random waves dates back to the 70's, see the WAFO background.
WAFO is freely redistributable software, see WAFO licence, cf. the GNU General Public License (GPL). .
