4.22 Setting Data File Quantities

By default, the information saved in a data file includes a standard set of quantities that were computed during the calculation, which are suitable for postprocessing in ANSYS FLUENT. If you plan to postprocess the data file in an application other than ANSYS FLUENT (e.g., ANSYS CFD-Post), however, you may want to include additional quantities. The additional quantities that are available are derived from the standard quantities.

The procedure for generating a data file with additional quantities is as follows:

1.   Set up the case file for your simulation.

2.   Initialize the solution using the Solution Initialization task page.

3.   Specify the quantities to be written in the data file, using the Data File Quantities dialog box (Figure  4.22.1).

(a)   View the Standard Quantities list to see what will be saved in the data file by default. Note that you cannot deselect any of the Standard Quantities.

(b)   Select the additional quantities you want saved from the Additional Quantities selection list.

(c)   Click OK.

4.   Save the case file. Note that the data file quantities you specified in the previous step will be saved as part of the case file.

5.   Run the calculation and save the data file. This can be done as separate steps, or as one step if you have enabled the automatic saving of data files via the Calculation Activities task page.

The Data File Quantities dialog box can also be opened by clicking the Data File Quantities... button in the Autosave Case/Data dialog box.
