Hi,

I trying to simulate various problems with OpenFoam and I am still in the learing phase. Perhaps somebody can help me.

I have a structure with an inlet of 4x5mm connected with a larger block. Attached to the block is a very thin outlet (0.2mm). I have created the structure with netgen and it is related to a problem a colleague of mine has.

I tried a simulation with simpleFoam and icoFoam and both simulations did not work. So far the mesh is very coarse, but I tried it als with a finer mesh.

In the attached file the whole icoFoam case is included with the netgen geo file. Running the case leads to an exploding courant number.

Thank you for your help, this is useful for me to get more knowledge about OpenFOAM.

Best regards
Stefan
