farazmardazad New Member faraz Join Date: Nov 2015 Posts: 8 Rep Power: 10	Hi all, I try to simulate an unsteady multiphase issue with vof model, but time step size for continuity convergence is order of e^10-6, and flow time is about an hour, so i can't simulate it because of very high computational expense. Are there a strategy to enhance time step size? thank you for answers.
