Question on open FSI in AcuSolve

Recommended Posts

Dear All:


I am trying to perform a CFD analysis for a building in wind with opening FSI. But I am afraid I didn’t see the building response (I thought the building should sway after I setting up the options related to FSI). Please see the following description. Thank you very much for your help.


I defined four nodes at the top of the building for getting time-history responses. And the velocity of the lower-left point in x-direction and y-direction (two horizontal directions), they are 0 all the time.






By opening the FSI, I did the following, would you please help me check if I missed something in the definition?


1.       Go to the Eigenmode Manager, import the modal analysis results from OptiStruct. The animation is shown in the following screenshot



2.       Change the wall boundary condition to “flexible body” and select “building” as the “Flexible body”

Did you go through the 'Transfer' process within the Eigenmode Manager?  You need to 'Transfer' the modal information to the 'Building' Simple BC.
