1.1.4 Starting ANSYS FLUENT on a Linux/UNIX System

There are two ways to start ANSYS FLUENT on a Linux/UNIX system:

• Start the solver from the command line without specifying a version, and then use FLUENT Launcher to choose the appropriate version along with other options. See Section  1.1.2 for details.

• Start the appropriate version from the command line by typing fluent 2d (for the 2D single-precision solver), fluent 3d (for the 3D single-precision solver), fluent 2ddp (for the 2D double-precision solver), or fluent 3ddp (for the 3D double-precision solver) at the prompt.

You can also start the parallel version of ANSYS FLUENT from the command line. To start the parallel version on x processors, type fluent version -tx at the prompt, replacing version with the desired solver version ( 2d, 3d, 2ddp, or 3ddp) and x with the number of processors (e.g., fluent 3d -t4 to run the 3D version on 4 processors). See Section  32.4 for more information about starting the parallel solvers.
