Hello
I have been performed a multiphase simulation using eulerian option. Primary phase is air and secondary phase is grain. in begining of simulation i patched volume fraction of granular phase as 0.5.
solution was diverged: Error: Divergence detected in AMG solver: pressure correctio. Error object:#f.
then for solving i removed the patching process. solution was converged.
what idea is proposed to convergence happened in patching option??
Any help would be thankful.

Hello
Thanks for your answer;
These factors were reduced to 0.1 or lower. but the problem was diverged.
please any suggestion??
