modal analysis by ansys using existing mesh
 

Hi, everyone,

I am working on a fluid-structure interaction problem of turbomachinery, I need to know the mode shape of the compressor blade.
My problem is that I have the surface mesh of the blade, which should not change. Can I using this mesh to do modal analysis and get mode shape of the blade surface using Ansys Mechanical ?

Any suggestion will be greatly appreciated.
Thank you very much
