Model - Dispersed Turbulence Flow – Table 15: DEFINE Macro Usage for the Eulerian
Model - Dispersed Turbulence Flow list the variables that can be customized using UDFs for the dispersed
turbulence flow Eulerian multiphase model, the DEFINE macros that are used to define the UDFs, and the phase that the
UDF must be hooked to for the given variable.
