Hi all,
I have been working on Solid-Liquid, Eulerian granular simulations for a good while now. My end goal is a solid-liquid-gas simulation.

The biggest problem is time.

I am simulating a 500k model, 3D (around 1/3 of the height is filled with solids, at a 0.6 packing ratio). And the time step for getting proper convergence stays very low (around 1E-5). At the same time, my upflow velocity is also quite low as well. What causes my simulation to take months for getting proper results (around 250 s). I am already using parallel simulations.

Are there any tricks, or other ways of running such case, in a more efficient way in Fluent?

Any recommendations are appreciated.
