Hi,

I have a problem in openfoam when I use a mesh with a geometric progression.

If I use the same fvscheme/fvsolution and boundary condition with a simple box I have no problem but If I had a geometric progression in order to have small cell somewhere, the calculation diverges.

I use rhosimplefoam but I have the same problem with other compressible solvers.


Someone has an idea of the problem ?

I can not upload my mesh but it's a simple box (20m - 5m - 5m) with a geometric progression in x coordinate (smaller cell = 4e-6m)

(sorry for my bad english)
Thank you for your attention.
