There is an option to solve these equations for a two-phase Eulerian-Eulerian system, and also for a multi-phase Eulerian-Lagrangian system using Lagrangian particle tracking to represent the particulate phases. These equations can be solved in cartesian, cylindrical-polar or body-fitted coordinate systems.
