Hello everyone !
I am working on OpenFOAM 4.1 and I am using interFoam to model a lateral spillway with two exits. See the attached image. https://drive.google.com/open?id=0B7...TdiekNuNjB1emM I have tried many set of BC for my outlets. Please see the excel chart. Some words are in French but it is quite explicit. https://drive.google.com/open?id=0B7...lJiNXc4MmlLSjQ I am struggling with the fact that : - either the simulation is doing well but one outlet is not emptying, or the two outlets are have very, very small outflow (such as 0.02 m3/s) - either the chamber seems to empty in both outlets but it encounters some diverging problem. I am monitoring U and P with fieldMinMax in controlDict and it shows exploding values ! checkMesh does not seem to report anything wrong. I have tried so many combinations of BC for the outlets that I am starting to wonder if it doesn't come from my mesh. Please, can anyone help ? I have been working on this case for three months now. |
