Hi,
I am new user of OpenFOAM-1.6. I can't find test for rhoSimpleFoam & sonicDyMFoam. Where I can find them?

Thanks in advance

Since OpenFOAM 1.7 you have to define rhoMax and rhoMin like you define pMin. Here is an example:

SIMPLE
{
nUCorrectors 2;
nNonOrthogonalCorrectors 0;
pMin pMin [1 -1 -2 0 0 0 0] 1000;
rhoMax rhoMax [1 -3 0 0 0] 2;
rhoMin rhoMin [1 -3 0 0 0] 0.001;

}

That worked great for that tutorial, thanks for the quick reply. I have used your case as a model for my geometry, and now I am getting this error.

Continuity error cannot be removed by adjusting the outflow.
Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow.
Total flux : 5914.4
Specified mass inflow : 30.8438
Specified mass outflow : 30.8437
Adjustable mass outflow : 0


Any Ideas? I have tried running potentialFoam, but it has the same problem. I have used your U boundry condition on the inlet, and also tried just a fixed value with similar results.

Thanks,
