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. /home/ifmg/Downloads/Screenshot.png |
