1.2.2 Background Execution on Windows Systems

To run ANSYS FLUENT in the background on a Windows system, the following commands can be used:

fluent 3d -g -i journal

fluent 3d -g -wait -i journal

fluent 3d -g -hidden -i journal

In these examples,

• fluent is the command you type to execute ANSYS FLUENT interactively.

• -g indicates that the program is to be run minimized in the taskbar.

• -i journal reads the specified journal file.

• -wait is the command you type in a DOS batch file or some other script in a situation where the script needs to wait until ANSYS FLUENT has completed its run.

• -hidden is similar to the -wait command, but also executes ANSYS FLUENT completely hidden and noninteractively.

To get an output (or transcript) file while running ANSYS FLUENT in the background on a Windows system, the journal file must contain the following command to write a transcript file:

; start transcript file
/file/start-transcript outputfile.trn

where the outputfile is a file that the background job will create and which will contain the output that ANSYS FLUENT would normally print to the screen (e.g., the menu prompts and residual reports).

See Section  4.10 for details about journal files. See Section  4.11 for details about transcript files.
