Before I get started I want to say that MFIX-Exa is not a friendly code. It does not have a GUI. It is a very high-level HPC code and basically can not be modified by a general user base. If you do not have experience with CFD and multiphase flow, this is not the code to learn on. I would recommend our classic MFiX code or a black-box commercial code for that. Further, if you don’t have a GPU to use or at least a few dozen CPUs, you’re are probably better off with MFiX classic. But, with that being said…
