MrNavierStokes New Member Alex Join Date: Jun 2015 Posts: 22 Rep Power: 0	Hello, I have a short question about the under-relaxation of variables. ANSYS Help Viewer: The under-realxation of equations, also known as implicit relaxation, is used in the pressure-based solver to stabilize the convergence behavior ... So what exactly is the difference to the under-relaxation of variables (explicit relaxation). When should I consider to change the URF for the pressure for example? Regards
