ohkk..i am using FLUENT 6.3 for simulation and GAMBIT 2.4 for meshing and drawing.
i am working on a close box which is 40% filled with water and heated from bottom.. There is 1 pressure outlet on the upper side of box and no flowing situation of air or water. By using VOF multiphase model i...
I am using VOF model for simulating..but within 1 or 2 time step courant number reach its limit and iteration stops..i reduced the time step size from 1 to 0.05 but there is no result of it..and i have to simulate it for around 1hour..
how can it be possible to increase courant number..or what...
