HP Guest Posts: n/a	Dear CFD users, I am on a multiphase Eulerian, unsteady case for which the proper time step is refered to be about 1e-3 to 1e-4. I noticed that if I strongly underelax the momentum equation (0.005!) the solution easily converges for a time step of 0.1s! Why this is happening? Is the physics of the solution affected? Thank you for your response, HP
