Is what happens in the first cycle important? Or just what the flow settles down to after a lot of cycles? But have you considered my comment in post #22? What dos the solid make any difference...

Are you trying to model the periodic steady state result (ie the result after many pressure cycles) or do you want the start up transient?

Obviously there is some problem with the way the solid is being coupled to the flow. I would check that the heat transfer between the fluid and solid is correctly modelled. But it is hard to be sure...

Mesh quality in solid regions is not too important. You have to have a really terrible mesh before it causes problems. The reason for this is in the maths - in...

On the fluid side you need to do the normal mesh density checks, and check the y+ is right. On the solid side just check the mesh is fine enough to resolve the gradients. You will be able to use a...

Do a mesh sensitivity study to determine it. The most important parameter is to have sufficient resolution to resolve the spatial and temporal transients you expect.

In solid regions the requirements on mesh are quite different to fluid regions. The equations to solve are well behaved numerically (no non-linear bits) which means that mesh quality is much less of...
