A step-by-step method to make a CFD simulation in commercial package CFX is explained below. The corresponding utilities in OpenFOAM are also described.

The simulation process is explained using Graphics User Interface (GUI) including basic settings of the GUI. These pictorial descriptions are grouped into 4 categories:
  • Basic settings on the Graphics User Interface to suit one's style
  • Pre-processing stage
  • Solver setting and Solution Process
  • Post-processing Stage

Note that ICEM-CFD can be assumed equivalent to blockMesh command line utility and CFX-Post is equivalent to ParaView. Hence, the feature of these two programs are at the moment not included. Thus, this page will mainly try to describe the equavalent of "GUI Operation in CFX Pre and CFX Solve" to "OpenFOAM 0/, constant/ and system/" folders.
