CFD Simulations

CFX and OpenFOAM

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 in OpenFOAM 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 equivalent of "GUI Operation in CFX Pre and CFX Solve" to "OpenFOAM 0/, constant/ and system/" folders.

Basic settings of the User Interface
CFX Gui - Basic Settings
Basic Setting: Import of Mesh

CFX Gui - Basic Settings
Basic Setting: Simulation Units. OpenFOAM operates only in SI units and hence all values must be specified in this unit system.

CFX Gui - Basic Settings
Basic Setting:Simulation Time Behaviour (Steady or Transient). OpenFOAM timestep can be used to make simulation transient or psuedo-transient [Steady State]

CFX Gui - Basic Settings
Basic Setting: Visualization (known as Rendering) of Mesh Elements. Click here for ParaView operations

CFX Gui - Basic Settings
Basic Setting: Screen Background and Global Axes of the Simulation Domain

CFX Gui - Basic Settings
Basic Setting: Default Action by the Software. Every program has some default setting which can be changed as per user's need. Click here for ParaView operations

CFX Gui - Basic Settings
Basic Setting: Default Actions when Mesh is Imported into CFX GUI. Refer to this section to patch operations in OpenFOAM
