We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Ashish,

Rob told me to contact you on this thread as an FSI expert.

I would say keep the Mechanical model even if bearing has negligible deformation, since in Mechanical you can model mechanical contact between deformable bodies. For FSI you need a contact region defined (frictionless type with offset defined with value equal to the gap you want to maintain so that the CFD mesh doesn't squash). I don't see a contact region defined in the above pictures.

As for the periodic interface, this is fine if the flow is periodic and it gives you accurate bearing loads. No problem from FSI perspective.

Paul
