Kombinator New Member Artem Join Date: Apr 2014 Posts: 29 Rep Power: 12	Dear all, I am new with openFOAM and I am trying to implement the following boundary condition at the conducting wall: $\frac{\partial\varphi}{\partial n}$ = a $\cdot$ $\nabla^{2}_{t}$ $\varphi$ where $\varphi$ is electric potential, a is constant, $\nabla^{2}_{t}$ $\varphi$ is tangential Laplacian at the wall. I wonder if anybody has an idea about the following question: Is it possible to find tangential Laplacian at the wall in openFOAM and if so - how? I guess that it is only possible to find normal Laplacian, but I will be happy if I am wrong. Thanks in advance. Best regards, Tar Last edited by Kombinator; July 18, 2018 at 17:06.
