33.16.1 Autosave Dialog Box

The Autosave dialog box allows you to specify automatic saving of case and data files at specified intervals during a calculation. See Section  4.3.4 for details.

Controls

Save Data File Every   specifies the frequency with which data files are saved. For steady flows you will specify the frequency in iterations, while for unsteady flows you will specify it in time steps (unless you are using the explicit time stepping formulation, in which case you will specify the frequency in iterations). The default value is set to zero, indicating that no automatic saving is performed.

When the Data File is saved, Save the Case   gives you the choice to save the case file only if it is modified or each time that the data file is saved.

If Modified During the Calculation or Manually   will result in ANSYS FLUENT saving a case file whether you make a manual change, or if ANSYS FLUENT makes a change to the code internally during the calculation.

Each Time   allows you to save the case file every time the data file is saved.

Retain Only the Most Recent Files   allows you to restrict the number of files saved by ANSYS FLUENT if you have limited disk space. When this option is enabled, you can enter the appropriate value in the Maximum Number of Data Files field.

  Only the associated case files are retained when using this option.

Data File Quantities   opens the Data File Quantities dialog box where you can specify which quantities you want to automatically save to a data file for postprocessing.

Maximum Number of Data Files   specifies the maximum number of data files that can be saved at any instance. If you have constraints on the disk space, you can restrict the number of files to be saved using this field. After saving the specified number of files, ANSYS FLUENT will overwrite the earliest existing file. The default value for this field is zero which saves all the files.

File Name   specifies the root name for the files that are saved. The iteration or time-step number and an appropriate suffix ( .cas or .dat) will be added to the specified root name. If the specified File Name ends in .gz or .Z, appropriate file compression will be performed. (See Section  4.1.5 for details about file compression.)

Append File Name with   allows you to select flow-time or time-step to be appended to the file name. This option is available only for unsteady-state calculations. The default selection is flow-time.

Decimal Places in File Name   allows you to specify the number of decimal digits in the file name. This option is available only when flow-time is selected in the Append File Name with drop-down list. The default value for this field is set to 6.

The Autosave dialog box is slightly different when running ANSYS FLUENT within ANSYS Workbench. For more information, see the separate FLUENT in Workbench User's Guide.
