Good Day to all,

[Apologies for my ignorance; still a beginner.]

Need your help as you can see in the attachments (extremely basic & raw model, just to establish the idea), the intention is to observe a fluid induced moment/ rotation in the disc/ plate. The disc here is modeled as Rigid Body (Immersed Solid), the housing/ pipe as immersed solid. IDEALLY, the extrusion on the ID of the pipe is meant to stop the disc during clockwise motion, on the other hand the inner surface of the pipe should act as a stop to the rigid body motion during excess anti clockwise motion.

I do realize & have learnt from the forum/ CFD sources that immersed solids are actually only scaling momentum (not solid domain bodies), hence cannot be interfaced or interact with other immersed solids (as observed the disc clearly does not respect the pipe ID and boundaries of the stop).

I would like to request ideas on the fact that, is there no way then at all in CFX to model the rigid body motion specially considering the interaction with other solids/ immersed solids/ rigid bodies..?? And if at all the rigid bodies can interact, then would FSI still remain applicable (tried importing pressure in Static Structural but does not show any CFD surface)??

To summarize,
- If i attempt to model the system using Solid domain, that would compromise the rigid body modelling/ flow induced motion
- If rigid body domain is employed, FSI and interface is compromised

Could really use some ideas here fellow users.

P.S. CCL file (plate.txt) is attached for reference.

Cheers.
