This forum if for discussing controls. Questions about how to implement controls in FAST are more appropriate to the CAE Tools forum.

How do specifie the translation direction of TMDs ?

Postby Laic.Wang » Sat Jul 11, 2020 3:24 am

Dear All

I recently read an article that mentioned that the translation direction of TMD is rotated by 45°about the vertical axis, forming an ‘‘X’’ . I am very interested in this. But after consulting the manual and the forum, no relevant problems were found. So ask everyone here.

Dear Laic,

The current TMD model in FAST / OpenFAST allows for two independent TMDs in the fore-aft and side-side directions, or one omnidirectional TMD. You'd have to change the source code a bit if you want to rotate the two independent TMDs by 45 degrees about the vertical xis.

Dear Jason,


Thank you for your kind reminder. I will try to change the source code a bit.


Best regards,


Laic
