I am working with a sliding mesh to simulate a fan. I am using a mesh interface between the moving zone and the non-moving zone. However, fluid does not appear to be passing through the zone, and the simulation diverges after about 20 iterations. Has anyone seen this before?

I have gotten this to work recently, then I changed the geometry, remeshed, and used the same settings. This time however, no luck. I think this is a bug, but possible I am making a simple mistake. Has anyone seen this before?

Dear Mach zero
what is your boundary condition in inlet and outlet? is divergence on mass balance?

Regards

Hi MachZero
you should check interface bc in your mesh generation software.
first plz check element size of mesh in two sides of interface.
