Divergence in AMG solver
Hi
I am trying to run a pipe flow case with finer grid,after few iterations, it gives divergence in AMG solver.In residual plot, I see that the continuity curve is diverging. The same case is running fine with coarse mesh size. your help in this regard is appreciated. Thanks Sri. |

Re: Divergence in AMG solver
Please also check the grid size ratio... Try to avoid long cells (the best possible are square like cells)
