update boundary load after deformation of the geometry in FSI

Please login with a confirmed email address before reporting spam

Hello,

my 3D model consists of three physics: Thermoacoustics, Solid Mechanics, and Laminar Flow. two multiphysics: Acoustic-solid interaction, Fluid-solid interaction (which uses Moving Mesh(ALE)). I defined a stress that uses variables from acoustics and I use that as boundary load(Force Per Area) in solid mechanics, I need to update that BL after 0.1s by solving acoustics on the deformed geometry. I tried deformed configuration mesh(Mesh2) but it's giving wrong results for acoustics, I also imported deformed geometry and solved acoustics on it but FSI could not solve(undefined value: spatial.u, spatial.v, spatial.w), also solved acoustics on the deformed geometry(imported) Mesh1 and FSI on Mesh2 but it fails to find a source point. I'm wondering if it is possible in comsol.

Sincerely,

Mohammad

My issue is simple, I want to calculate force in the deformed Geometry and then apply it in FSI with initial condition (previous solution). please help!!!
