Hi,

I recently updated to Fluent 15.0 and I am facing a weird problem. For some of my cases I get a converged solution in fluent 14.5.7 (and any older version) but they don't converge (and some times diverge) in version 15.0. I tried to set up the cases from scratch, I even regenerated the mesh using ICEM CFD 15.0, but I still have this problem.

I have noticed that this happens when I have large number of low quality cells in my mesh (due to the prism layer, etc.) I think version 15 can not handle low quality cells as good as older versions...!

Does anyone else faces the same issue? Any idea why it is happening?

Thanks
