General mode is the general-purpose mode for defining all types of CFD simulation. This mode uses the general CFX-Pre interface, which is described in Working with the CFX-Pre Interface.

Turbomachinery mode is a customized mode for defining turbomachinery simulations. For details, see Turbomachinery Mode.

Quick Setup mode greatly simplifies the physics setup for a simulation. Quick Setup mode is limited to a single-domain and single-phase problems; more complex physics, such as multiphase, combustion, radiation, advanced turbulence models, and so on are not available. You can, however, use Quick Setup mode to get started, and then add more physics details later. For details, see Quick Setup Mode.

Library Template mode provides a set of library files that are available with templates for specific physical problem definitions. In this mode you can easily define a complex physics problem by loading a template file, importing a mesh, and defining specific problem data. For details, see Library Objects.
