Hi there,

I'm trying to calculate permeability across a mesh using simpleFoam as the transport model. I've already received some help with a floating point error due to diverging solution but I'm wondering what the best boundary conditions to use are and how this will help my solution as it's currently still diverging (just not as quickly as it was!)

Case file can be found here:

the zmin-wall is the inlet patch and the zmax-wall is the outlet patch.

Mesh quality is ok (created in ScanIP and checkMesh says OK)

All I really want is a simple laminar flow through this mesh which I thought would be simple!
