Hi, I am modeling a pipe flow containing a restrictor. A thin gap with about 0.1 mm hight occurs. My question is what should be the minimum amount of elements in this gap regarding hight) for good results with sst?

Hi,

There is no general answer to that question as it depends on the flow, geometry and lots of other things. Do a mesh refinement study on it and find out.

Ey thx I am trying. Leads me to the next problem. Refining the mesh leads the mesh to creep out of the body at narrow overlapping surfaces. Possible to avoid that?

Hi,

In ICEM have a look at thin cuts (I think that is what they are called). CFX-Mesh should not have this problem.
