## Chapter 2: Overview of ANSYS CFX

ANSYS CFX is a general purpose Computational Fluid Dynamics (CFD) software suite that combines an advanced solver with powerful preprocessing and postprocessing capabilities. It includes the following features:

- An advanced coupled solver that is both reliable and robust.

- Full integration of problem definition, analysis, and results presentation.

- An intuitive and interactive setup process, using menus and advanced graphics.

ANSYS CFX is capable of modeling:

- Steady-state and transient flows

- Laminar and turbulent flows

- Subsonic, transonic and supersonic flows

- Heat transfer and thermal radiation

- Buoyancy

- Non-Newtonian flows

- Transport of non-reacting scalar components

- Multiphase flows

- Combustion

- Flows in multiple frames of reference

- Particle tracking.
