Multiphase VOF not converging

I am simulating a steady state stratified two phase 2D channel flow with periodic boundary conditions.
The residuals (all) oscillate for the default values of URFs. However, when I reduce the residuals of k, w & P to 0.1 the oscillations vanish and the solution converges (extremely slowly). Is it advisable to do so? P.S: I have changed grid sizes, ran unsteady state simulations. Nothing seems to prevent the oscillations when the URFs are at default values. |
