Hello,
I am trying to understand how to set-up my case in COMSOL. Assume that you have a sphere that is located in a box. The sphere is rotating with X rpm in the box. Do you use the rotating machinery module and using the moving mesh in COMSOL at the boundary of the stationary and moving domains? or you just consider stationary domain and give no slip boundary condition with moving wall values (V=rw) at the interface without considering the moving mesh and domain?
Also, if my geometry is an assembly, do you use form assmebly or union in my case? I am thinking of from assembly as I have better control on my mesh (different domains with various mesh control). Does this approach make sense?
I need to solve heat trasnfer and fluid mechanics (CFD) in my study.
Thank you,
