Hello,
I am investigating coarse grained methods and would like to start with the integrated Solver using the Mfix GUI. I found the tutorial, but can’t seem to find any explanation for the tutorial nor the solver ?
Are there any theoretical descriptions ?
Best regards,
Janna

Coarse Grain DEM [1]: Eulerian/Lagrangian model similar to DEM, where particles are grouped into larger coarse-grained particles (CGP). It is more affordable than DEM since fewer CGPs need to be tracked. The collisions between CGPs are resolved the same way as in DEM. This modeling approach falls between DEM and PIC in terms of computational resources.
