1.3.3 Batch Execution Options

During a typical session, FLUENT may require feedback from you in the event of a problem it encounters. FLUENT usually communicates problems or questions through the use of Error dialog boxes, Warning dialog boxes, or Question dialog boxes. While executing FLUENT in batch mode, you may want to suppress this type of interaction in order to, for example, create journal files more easily.

There are three common batch configuration options available to you when running FLUENT in batch mode. You can access these options using the Batch Options panel .

File $\rightarrow$ Batch Options...

Figure 1.3.1: The Batch Options Panel

The Batch Options panel contains the following items:

Confirm File Overwrite   determines whether FLUENT confirms a file overwrite. This option is turned on by default.

Hide Questions   allows you to hide Question dialog boxes. This option is turned off by default.

Exit on Error   allows you to automatically exit from batch mode when an error occurs. This option is turned off by default.

Note that these options are also available in the file/set-batch-options command in the text interface.

file $\rightarrow$ set-batch-options

Any combination of these options can be turned on or off at any given time prior to running in batch mode.


Batch option settings are not saved with case files. They are meant to apply for the duration of the current FLUENT session only. If you read in additional mesh or case files during this session, the batch option settings will not be altered. As batch options are not saved with case files, journal files developed for use in batch mode should begin by enabling the desired batch option settings (if different from the default settings).
