I am working on my master thesis, which concerns developing a floating support structure for a wind turbine with an elliptical tower cross section and a yaw bearing at the tower base. I am thinking of several possible support structure concepts (barge, TLP, buoy or semi-submersible) and I have to calculate the hydrodynamic loads on the submerged structure. I can see from the test 22, 23 and 24 files that the hydrodynamic loads are frequency dependent and have been calculated using the software WAMIT. Unfortunately, my institution does not have a license for WAMIT and I now ask if anyone know of a free, open-source software that can generate the same type of files as WAMIT (.hst, .1 and .3) that can be read by FAST8? I have looked a little into NEMOH, but it does not appear to be able to generate the 3 file types needed for FAST8.
