Free output Velocity - icoFOAM
Hi,
I'm new in OpenFOAM. I'm running icoFOAM for a Y-geometry (cylinders) but I have this error: "floting point exception". In fact I have a really huge Courant number even if I have a small deltaT (0.00001). How can I solve this kind of problem? In addition I'd like to have free velocity in both outlets, any help?? These are my 0\p and 0\U files: dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { inlet { type fixedValue; value uniform 56291.66e5; } outlet { type fixedValue; value uniform 56289.67e5; } wall { type zeroGradient; } } // ************************************************** *********************** // dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { inlet { type fixedValue; value uniform (0 0 4.94745); } outlet { type fixedValue; value uniform (0 0 1.44048); } wall { type fixedValue; value uniform (0 0 0); } } // ************************************************** *********************** // |

Now I have a turbolent flow so simpleFoam should be better, does 'zeroGrandient' work for the outlet 'free velocity' in this new case?
Thank you so much. |
