Prepare the test case properly and post it here. After that I may take a look on it. BR Martin |

Which case do you mean because at the begining i posted my valve studying case problem . After that i posted just a simple case to generalize my problem which is just a cylinder see post #18. So i thought that you told me about the simple case which is just a cyliner and i had the same problem at the interface between the inlet and the wall with elements with very high pressure. |

Hi Mina
I changed divScheme by adding bounded to the terms with phi and it seems run without problem. Code:
divSchemes
{
default none;
div(phi,U) bounded Gauss GammaV 0.5; //was 0.5 1.0
div(phi,k) bounded Gauss limitedLinear 1;
div(phi,epsilon) bounded Gauss limitedLinear 1;
//div((nuEff*dev(grad(U).T()))) Gauss linear;
div((nuEff*dev(T(grad(U))))) Gauss linear;
//div((nuEff*dev(grad(U).T()))) Gauss linear faceMDLimited Gauss linear 0.85;
//div(phi,U) Gauss linearUpwindV faceMDLimited linear 0.68; //was 0.5 1.0
//div(phi,k) Gauss linearUpwind faceMDLimited Gauss linear 0.2;
//div(phi,epsilon) Gauss linearUpwind faceMDLimited Gauss linear 0.91;
//div((nuEff*dev(grad(U).T()))) Gauss linearUpwind faceMDLimited Gauss linear 0.85;
}

I tried also with your folders (0 , constant, system) but I got the same error
 don't know why Quote:

you use 2.1.1 vesion? download 2.2.0 or 2.2.1 version so that can run.

I used OpenFoam 2.2 and finally, I didn't have this error. But after launching Paraview, I realised that my problem didn't been solved. Here are the attachement that i got with elements at the interface between the inlet and wall with high pressure ! |

why youe mesh is so coarse? use a finer mesh and see if changes.
