nks is on a distinguished road
I am implementing k-eps and v2-f model for buoyant flow inside cavity. At the 4 walls, bcs k=0, v2=0. As such the values of k and v2 and hence turbulent viscosity are going to nearly zero, although the equations for these have source terms. Anybody out there with a remedy!!??!!
