I am facing problem in convergence of three-phase (2 granular solids) granular flow using eulerian multiphase model.
The problem is, when i use two granular solids with density difference (ie 500 kg/m3 and 2600 kg/m3), the simulations don't converge as residuals for granular temperature diverge and hence continuity as well. When i use 2 granular solids with almost same densities, there is no problem. I have tried reducing density under-relaxation to 0.1 from 1, still of no use. Please help. Struck on this issue for over a month. |
