Does anyone know what advantages Fluent's Macroscopic Particle Model (MPM) has over Star CCM's Discrete Element Method (DEM) when it comes to modelling multi-phase flow containing super-grid particles (i.e. those larger than the minimum mesh size)? I understand that both exhibit four-way coupling, but DEM also allows for the deformation of particles to be accounted for where MPM does not, so I can't seem to think of many instances where MPM is preferable? Is the only advantage that MPM is less computationally intense (I'm assuming this is probably the case)? Or are there other ways in which MPM is advantageous?
