Servus,

I have tried out a icoTopoFoam case. I began at the mixer2D tutorial. Then I changed the mesh like in this case http://www.cfd-online.com/OpenFOAM_D...tml?1123794946 But not radial only axial and very simple only with 32 points. I have made like a rotor/stator with each three blocks. Before and behind the blades the boundary condition is cycil. The sliding b.c. is betwenn rotor and stator.
Do I need the celltoRegion file?

The configuration is running, but is than aborted. The failure is like:

Can anyone help me?

I can also post the b.c. and the blockMeshDict if it is helpful.

If I get the case to be run. I can it post as a turbomachinery tutorial.
