Hi,

I tried to solve incompressible NSEs on lid cavity problem and the results look fine (simple algorithm, collocated). However, when I switch to backward facing step problem, the solution can not converge. The things confuse me most are the boundary conditions of pressure correlation/velocity-u at inlet and outlet.

So, is there any one can make a short summary for me about the correct BC setting for backward facing step problem.

Thanks in advance!
