Hi all
i am using vof model and explicit vof scheme..
i have the problem with the convergence of x, y, z velocity this are not going down with time step rather increasing but continuity equation converges... and one more thing when i using implicit scheme after 3 or 4 time step it gives an error that divergence in AMG solver:x momentum...because of it i am using explicit scheme with very low time step size. how i encounter this problem and use implicit solver with large time step???????
