MigFlow (https://www.migflow.be)

MigFlow is a free and open source software dedicated to the simulations, in complex geometry, of immersed granular flows (mixture fluid-grains) presenting a large discrepancy in the solid volume fraction going from pure fluid to porous media. The fluid is solved using the finite element method at a greater scale than the grain scale while the grains are solved using the discrete element method to obtain accurate representation of the local effects due to the grains configuration.
