Hi,
I have had problems finding a working kOmegaSSTDES example, so I tried to modify the simpleFoam/motorBike tutorial to pimpleFoam with kOmegaSSTDES. After a few iterations the simulation blows up. What do I do wrong? Shoulld the wall boundary conditions be modified? Best regards, Per |

The problem appears to be that kOmegaSSTDES is very sensitive to strong gradients.
I go it to work by slowly ramping up the speed. The method used in the other motorcycle example with precalculating a static solution as initial value does not seem to work here... |
