Hello everyone, the new computer I use runs for the first time, and the following problem occurs (in attachments). How can I solve it?

Dear Jason,
If I have to rotate the platform, only modify HydroDyn (MEMBER JOINTS) and MoorDyn through rotation. Is it correct?

Dear Jason,
I want to rotate the platform by an angle (see attachments). Where should I modify it? Which parameters need to be modified? Thank you for taking the time to help me answer it.

Dear Jason,
Thank you for your reply. I set the decay-test simulation time to 1200s, and the surge natural period is really about 107s.Is the simulation time bigger the better?

Dear Jason,
The free decay simulation time is 600s, and the results are shown in the attachment.

Dear Jason, (1) My settings are: Disable CompInflow, CompAero; Ptfmsurge=5, (Ptfmsway, Ptfmheave, Ptfmroll, ptfmpitch, ptfmyaw=0), Wavemod=0; Using Jason_PSD to analyze the surge time-series, the spike corresponds to the natural frequency. (2) Because I also passed the irregular wave verification an...

Dear Jason, Thank you for your quick reply. I used the NREL5WM semi-submersible floating wind turbines and did not modify the parameters of the model. Is the surge natural period correct? If I want to modify the model, where is the additional mass modified? Is it to modify the value of AddF0 in Hydr...

Good mooring, I directly downloaded the latest version of OpenFAST 2.4.0, and used it to do a free decay test of a 5WM semi-submersible wind turbine. I found that its surge natural period was 120s, but I read other papers about 107s. What is the reason? If I want to use OpenFAST to compare with prev...
