Mathematical eq. for symmetric boundary -- CFD Online Discussion Forums

Nestor Guest Posts: n/a	Hi all! I am writing a small code to solve the laplacian equation over a 2D domain with a symmetry plane. The thing is that I am not sure what is the equation that holds for these nodes. I thought and probably is right that the equation is: du/dn = 0 ( homogeneus von Neumann BC). is it right? Thanks in advance
