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.
