Co simulation in starccm with Abaqus
 

Hi. I am trying to solve FSI problem in starccm for a rotating body with abaqus. The MRF is used to obtain the pressure load form CFD and it is fed to the FEA. In view of that morphing is used. But i am not able to do the simulation because in get negative volumes due to body rotation. In MRF method the body should not rotate. Kindly help me out form this:confused::confused::confused:

In MRF method, Body is not moving.
Just add some forces in calculation like some parts are really rotating.
So, I think MRF is the useful solution for your problem.

If you should show the rotation part is really moving.
you can choose 2 ways to solve that.

Morphing and Overset.

If you choose overset, you should make many cells for interface boundary to capture rotating body but you don't need 'remeshing'

If you use morphing for that. you should remesh many times for cell quality..

I don't recommand morphing

My problem is not about the body. The body should be stationary similar to a propeller tutorial in starccm+. this should ideally give the body pressures and the same shall be transferred to the fea module. my problem lies with morphing which inducing rotation.
