use LLFVW calculate OC4

Dear Pro.Marten

I loaded the OC4 example and set the wind and linear wave, but the calculation results showed that all the 6-DOF motions of the platform were 0. I wondered whether I had neglected any Settings?

Best regards,

Hi,

the sensors you are looking at are not showing what you are expecting. I would agree that this could be a bit misleading, but the “Platform Translation” sensors only show a “prescribed motion” of the floater. Prescribed motions can be assigned to a floater using prescribed motion files or actuators. In your case you find the platform motions located in the “Hydrodynamic Time Graphs”. Just switch any graph to the “Hydrodynamic Time Graph” type using the right mouse button.

BR,

David

Hi robytian, just right click or double click on the graph, you can choose the parameters you want, I think the NP …(trans or pith) is that you want.
