Overview

These tutorials walk through setting up, running, and analyzing MFIX-Exa cases, starting from simple, well-characterized flows and building toward more complex setups. Each tutorial includes the complete a description of the important input sections, and an analysis of the results.

Tutorials are grouped by the physical model they use. Within each category, tutorials vary in which additional physical capabilities they exercise – for example, the energy equation, species transport, reactions, or a rotating reference frame. The table below summarizes this across all tutorials.
