SubscriberIs there any reason solid cell zone sources will not generated heat when used in multiple reference frames. I've always run conjugate heat transfer problems with one reference frame, modelling the rotating components as moving walls. However, in an attempt to get a better idea of the effect of a non tangent rotating wall, I have used a multiple reference frame. The solid cell zones with sources are not generating any heat. I have simply read the same settings file but made adjustments for the rotating fluid zone. Any thoughts?

Ansys EmployeeHi Nicholas,
Are you providing rotation to your solid cell zone as well. If you are facing issue with frame motion in solid zone, I would recommand using moving mesh/sliding mesh or else cell zones may become disconnected.
Note that a solid zone cannot move at a different speed than an adjacent solid zone; for such a situation, you must instead use Solid Motion.
If I got your question wrong, could you please share more details on how you are setting up the frame motion and source term in solid cell zone.

SubscriberThank you, it was actually pseudo time settings. After that was corrected, convergence was ok. Still running into some flux errors across interfaces and trying to find best way to mitigate

Ansys EmployeeAre you using conformal or non-conformal interface? Can you try with hex or poly mesh. It is also recommended to use a refined mesh.

SubscriberUsing non-conformal interface and poly mesh. I will try refining the mesh first and see if that improves
