Hi,
I'm simulating a flow though an volute casing.
I'm in the initial stages of showing grid independence.
the k-epsilon model was working fine until the no. of elements was around 2.5 lakhs.
in the 4 lakh element model im not getting a converged solution.
the residuals for continuity are not stable now.
I'm using the simple algorithm, with 2nd order upwind diff(used 1st order too; but same problem) 0.5 relaxation. its a single-phase flow.

Please suggest ways to converge this solution.
