Hi Foamers,
I am really struggling with simulating the contaminant transport in water by using the new function object phaseScalarTransport in interFoam. I have read some threads on this topic in the forum and been trying to modifiy the controlDict in my own case, but the results are quite ridiculous, which is incomprehensible for me. Here is my codes of phaseScalarTransport function and the results of the simulation in 5s : Code:
scalarTransport { type phaseScalarTransport; libs ("libsolverFunctionObjects.so"); enabled true; writeControl writeTime; writeInterval 1; rho rho; phase alpha.water; field s.water; diffusion viscosity; alphal 1; alphat 1; nut nut; resetOnStartUp no; } |

Hi Thomas,
My first guess would be about the discretisation scheme you use for the convection of the scalar. You will need some stabilization on that term typically. It looks like you now have too little of that and then you can get unbounded results. Cheers, Tom |
