Hello,

Is a description of the FAST \*.outb files available? I tried the link [wind-dev.nrel.gov/bugzilla/show\_bug.cgi?id=150](https://wind-dev.nrel.gov/bugzilla/show_bug.cgi?id=150) that I found in the FAST changelog.txt but it doesnt work?

best regards,  
Gerrit

Hi, Gerrit.

The only description currently available is in the matlab script, ReadFASTbinary.m (though the code is in MCrunch and Crunch, too). ReadFASTbinary.m is in the FAST archive. The file is distributed in FAST v7’s CertTest folder and FAST v8’s Utilities/SimulationToolbox/Ulilities folder.
