rhoPimpleFoam error
Hi,
I am running a a case with low velocities around 40m/s and temperature abt 295K but very turbulent flow. This should be an incompressible case, I get this error message after several runs. I have tried to limit the density but this does not help either. Could anyone please help me with this problem?

I guess your initial conditions make some problems.
If rhoSimplecFoam runs successfully, you can run it at first and then set the response as the initial condition for rhoPimpleFoam. (I have done it before) |

now my case runs with my own boundary and initial conditions. without using rhosimplecfoam. if only openfoam had a good help :( |
