mhdmk is on a distinguished road
Hello

i want to simulate a supersonic Air flow that is injected in to a water tank. i used both mixture and Eulerian methods. but in simulation when air is reaching to high much number and injected in water the solution is diverged. i set the under relaxation factor at very numbers(0.1or0.2) but the problem still is not converged. so has anyone faced this problem before?

best regards
