Hi

In my problem there is a cylinder ( about 1m long and 0.4 m dia.) with two inlets and two outlets. Two immscible fluids enters at opposite ends( lighter liquid from lower inlet and heavy liquid from upper inlet)and after some agitation two stream leaves the cylinder ( lighter stream from upper outlet and heavy stream from lower outlet). I am facing difficulties in convergence of the problem.I think I may have made mistake while defining boundary conditions. Can anybody suggest how to define boundary conditions in such cases?
