Center of Mass / volume

I'm trying to add the calculation of the center of mass in the solver InterFoam. I wrote in interFoam.C :
vector CoM = sum(mesh.V()*(alpha1*rho1 + (1-alpha1)*rho2)*mesh.C().internalField())/sum(mesh.V()*(alpha1*rho1+(1-alpha1)*rho2));
vector CoV = sum(mesh.V()*mesh.C().internalField())/sum(mesh.V());
I can't see the probleme. If the first line compile, the second should too. Does anyone of you have any idea ?
After some tests it seems the problem is coming from "mesh.C().internalField()". As soon as I use this in the "sum" operator, the dimensions are deleted.
- sum(rho*mesh.V()) -> dimension is kg.
- sum(rho*mesh.V()*mesh.C().internalField() -> dimmensionless.
Is there a way to fix that ?
