I have a problem where Fluent will not start a case and immediately outputs "divergence detected in AMG solver"
I have narrowed the problem to very small cells in a certain region of my grid. I have a consistantly refined mesh and do not see these problems on coarser grids. Furthermore, I see this problem when using the Spalart-Allmaras turbulence model, but not some of the other turbulence models. My project is the validation the S-A model, so it is essential that I use it. Thanks for your time. |

This question has been answered a couple of times now I think. Do a search and you will get it.
