Hello! I want to implement the
 

Hello! I want to implement the following code to a application I have created. But Im not quite sure how to use the mesh.V() and mesh.Sf() functions.

label holePatchi = mesh.boundaryMesh().findPatchID("hole");

if (holePatchi != -1)
{
solve
(
fvm::div(phi, T)
- fvm::laplacian(alphaEff, T)
+mesh.V()*q/(rho*Cp*mesh.Sf())
);
}

else
{
solve
(
fvm::div(phi, T)
- fvm::laplacian(alphaEff, T)
);
}

In the if operation im interested in doing a calculation which involves multiplication with the surface area that is in contact with the patch called "hole" and im also intrested in dividing with the volume of this cell. When compiling this I get the following error message:

Could anybody please give me a hint in order to get this right?

Thanks

It seems as I need to definate the scalar * matrix operation differently from mesh.V()*q.

Does anyone know how to make this calculation?

Thanks
