ginette New Member Martine Ginette Join Date: Feb 2011 Posts: 5 Rep Power: 0	Dear everyone, Sorry for the stupid question: I am new to both Finite Volume and OpenFoam. I am solving some classical elliptic equation. The solution is a volScalarField. I also compute the flux, ie a volVectorField, through fvc::grad. Everything is fine except the value of the gradient at the border cells: much higher! I guess I am doing something wrong, but can't manage to find what. Many thanks in advance for your help, Martin.
