FAST Theory Manual

Dear Dr. Jonkman,

Is there a FAST Theory Manual? I need some background information as to formulas such as that for the TwFAStif, i.e. its derivation etc. and similarly for the other property formulas used in the software. In one of your presentations you mention an “unofficial theory manual” … Is this available?

Thanks,
Peter

Dear Peter,

Please see the topic on our forum found here for information on the FAST theory basis: Coupled blade modes in FAST (particularly, the Dec 15, 2010 amd Sep 12, 2012 posts).

Best regards,
