Hi,

I have two questiosn belonging the following code:

vectorField fN
(
rho(p)*Sfb[patchi]*(p.boundaryField()[patchi] - pRef)
);

  vectorField fT(Sfb[patchi] & devRhoReffb[patchi]);

Does anyone know what is meant by Sfb and RhoReffb or Reffb? I think Sfb is the area of the face i. "dev" subtracts the trace from the tensor. RhoReffb should be something like mu*grad(u).
