Hello everyone,

I'm willing to include a mass source term in twoPhaseEulerFoam solver :

S_Mass = - rho1 * alpha1 / dT, with dT the time step.

It should extract the mass of the phase1 (dispersed phase) in a zone I define with a function :
F = 1 if I activate the source term,
0 elsewhere.

That's for the theory. I'm stuck with the OpenFOAM code now.

Since the equation is in volumic form, I wrote :

alphaEqn :
(
fvm::ddt(alpha1)
- fvc::ddt(alpha1)
- fvm::laplacian
(
alpha1f*ppMagf,
alpha1,
"laplacian(alpha1PpMag,alpha1)"
)
==
scalar(-1)*F*alpha1/runTime.deltaT().value
);

pEqn :
(
fvm::laplacian(Dp,p) == fvc::div(phiHByA) + F*alpha1/(runTime.deltaT().value)
);


Does it seems correct to you ?


Thank you.
