CFD Online Discussion Forums - fvSolution setting for waves2foam

Dear all,

I'm currently looking into the setting in the fvSolution dictionary. I'm solving a 2D multiphase problem with free surface waves using waves2foam. Within the fvSolution dictionary I'm using the following settings for the alpha.water equation solver:

Code:

”alpha.water.∗ ”

{

nAlphaCorr 1;

nAlphSubCycles 1;

cAlpha 0.5;

alphaOnce true ;



MULESCorr yes;

nLimiterIter 3;



solver smoothSolver;

smoother symGaussSeidel ;

tolerance 1e −8;

relTol 0;

}

Can anyone give some insight on the alphaOnce true keyword?

Cheers,
Christian
