Extrusion with OpenFoam problem No. Iterations 0

Lord Kelvin · April 12, 2011, 06:50

Hi, I'm trying to simulate a laminar flow in a cylinder (hole of the extrusion die) with inlet and outlet (bases) and wall (lateral). I modeled it with Salome 5 (CAE linux) and exported the mesh in UNV.

I post the files:

I can't find the problem, the issue. Someone can help me?
