I’m trying to simulate a semisubmergible platform. I changed the wamit input files and the several parameters that concern to the platform. When I execute FAST, the most common error that appears is:
Value of Rzero = XXXX must be smaller than 1 in xphi().
Looking into the code, Rzero = radius of the turbine element/rotor radius.
I cannot understand why this is happening. I’m using the NREL 5MW turbine, so Rzero should be always less than 1.
Thank you very much for your help.
