Hello everyone,
When I runing POWER LAW or Quick scheme in my model, fluent give me the error: diverge in AMG solver: X-Momentum. I could not figure out what cause this problem. Does anybody give me a help on this error? For my case, first order and second order scheme works well. Because my grid is T-Grid, so I think power law scheme is better for my simulation. Any helps are appreciated. Thanks. Zwdi |

Check you boundary conditions to see if it is well defined.

Thanks, Wang. I used the same boundary conditions as upwind scheme. Do you mean if I change discrete scheme(upwind, power law, quick), I should change boundary conditions? Add one point: I use RSM turbulent model.
