Fluid Structure Interaction Problem
 
Hi!

I am working on a FSI problem. I use Numeca Fine/Turbo and Ansys for the simulation. I have mapped the cfd pressure data and import it to the Ansys. I want to check if the mapped cfd data and the meshes are matching properly. Could you please recommend me a way to compare these two?

Best Regards,

Bekir

Check if the resultant load is the same. This should be available both in CFD and structural solver. Usually meshes are not conformal and resultant load is the first quantity to observe to understand the job of the interpolator.
I have successfully used FSI mapping of Fluent (to map Fluent results onto Nastran FEM mesh). It works fine, but normals are to be properly oriented, check them carefully!

Thank you Marco!
