Hello,

When I run a case, an error occurred. The error information is as follows:

Error: divergence detected in AMG solver:x-momentum Error Object:#f

It is appreciated to share similar experience.

Thanks,

Tighten your under relaxation factors and then run. For instnace check on momemtum under relaxation factors now say its 0.5 tighten it to 0.1. Then this error should go away. However doing this increase your tun time. KP

For my case, it also happens when I changed to a parallel solver with auto partition. After I used Metis partition, it disappeared.

Thanks! using coupled solver and a smaller urf, the case is working.

Hello. i am doing a multiphase simulation in a packed bed using the mixture model. the volume fraction used was 0.5316.i keep getting the error message "divergence detected in AMG solver: x-momentum" for all the different solvers used and i even changed the under relaxation factors. i really have no idea how to proceed with this simulation!plzz help!thank u.
