Hi all,

I am new to OpenFOAM and CFD and for studying myself I want to compare OpenFOAM with Ansys CFX. In the Ansys CFX Help i found this case.

At first I've created the Mesh with blockMesh. Now I want to run the case without the heat transfer at the bottom with simpleFoam. I am using the same settings as in the pitzDaily tutorial. I've calculated k and epsilon with the formula 2.9 and 2.10 in the OpenFOAM help.

The problem now is, the calculation does converge after 432 iterations but takes a very long time. About 1871 seconds.

The system is a Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz with 4 GB Ram.

thanks!
