Appendix A. Ansys Fluent Model Compatibility

The following tables summarize the compatibility of several Ansys Fluent model categories:

Multiphase Models (see Modeling Multiphase Flows)
Moving Domain Models (See Modeling Flows with Moving Reference Frames)
Turbulence Models (See Modeling Turbulence)
Combustion Models (See Chapters Modeling Species Transport and Finite-Rate Chemistry – Modeling Engine Ignition)

Note that a ✓ indicates that two models are compatible with each other, while the absence of a ✓ indicates that two models are not compatible with each other.
