2.6. Starting Ansys CFX Components from the Command Line

The components of Ansys CFX can all be started from the command line. A command consists of the path to the command, the command name, and various arguments, many of which are optional.

For example, to start up CFX-Pre and play a session file named StaticMixer.pre, open a terminal window and enter the command:

<CFXROOT>/bin/cfx5pre -play StaticMixer.pre

where <CFXROOT> is the path to your installation of CFX, for example C:\Program Files\ANSYS Inc\V242\CFX on Windows.

The following table lists some of the commands you can use to start Ansys CFX components:

Component	Command	Arguments
Ansys CFX Launcher	`cfx5` or `cfx5launch`	See Starting the Ansys CFX Launcher.
CFX-Pre	`cfx5pre`	See Starting CFX-Pre from the Command Line in the CFX-Pre User's Guide.
