Hi, I keep getting this error message when trying to begin iterations in Fluent. What does it mean please?
Error: divergence detected in AMG solver: x-momentum Error Object: () iter time/iter |

Hey Naghman
AMG is the Algebraic MultiGrid solver. (basically the solver) Your solution is not converging. Start with lowering the under-relaxation factors in the (Solve-->controls-->solution) panel. Also, make sure that density is not assigned as a "constant" if your model involves temperature gradients or compressible flow. Good Luck! |
