Hi,

I use interFoam to simulate bubbles in glycerine, I obtained bad results, and I don't know what is the numerical problem. With water there aren't problems.

I use this

solvers
{
pcorr ICCG 1e-10 0;
pd ICCG 1e-10 0;
gamma BICCG 1e-12 0;
U BICCG 1e-08 0;
}

PISO
{
momentumPredictor yes;
nCorrectors 3;
nNonOrthogonalCorrectors 0;
nGammaCorr 1;
nGammaSubCycles 4;
cGamma 2;

Hallo,
your bubbles in interfoam are quite nice. I have a similar problem. I want to simulate the evaporation of a solid. Probably in order to get the bubbles you had to add a source term to the interfoam solver? Is that right? If yes can you tell me in which equation I have to add a source term in order to get bubbles?
Best regards,
Karl-Heinz
