4.15 Exporting Steady-State Particle History Data

Particle history data can be exported for steady-state solutions by selecting the Particle History Data... option under the File/Export menu and performing the steps described in this section. For details about exporting particle history data during transient simulations, see Section  4.16.

File $\rightarrow$ Export $\rightarrow$ Particle History Data...

Figure 4.15.1: The Export Particle History Data Dialog Box

1.   Specify the File Type of file you want to export by selecting one of the following:

• Standard for FIELDVIEW format

• EnSight format (not available when Unsteady Particle Tracking is enabled in the Discrete Phase Model dialog box)

• Geometry for .ibl format

If you plan to export particle data to EnSight, you should first verify that you have already written the files associated with the EnSight Case Gold file type by using the File/Export/Solution Data... menu option (see Section  4.14.9).

2.   Select the predefined injections that are the source of the particles from the Injections selection list. See Section  23.3.14 for details about creating injections.

3.   Select an appropriate category and variable under Quantity for the particle data to be exported.

4.   Enter the name (and folder path, if you do not want it to be written in the current folder) for the exported particle data file in the Particle File Name text box. Alternatively, you can specify it through the Select File dialog box, which is opened by clicking the Browse... button.

5.   If you selected EnSight under File Type, you should specify the EnSight Encas File Name. Use the Browse... button to select the .encas file that was created when you exported the file with the File/Export/Solution Data... menu option. The selected file will be modified and renamed as a new file that contains information about all of the related particle files that are generated during the export process (including geometry, velocity, scalars, particle and particle scalar files).

The name of the new file will be the root of the original file with .new appended to it (e.g., if test.encas is selected, a file named test.new.encas will be written). It is this new file that should be read into EnSight. If you do not specify a EnSight Encas File Name, then you will need to create an appropriate .encas file manually.

6.   If you selected EnSight under File Type, enter the Number of Particle Time Steps.

7.   Click Write to export the particle history data. If you selected EnSight under File Type, data files will be written in both .mpg and .mscl formats.

8.   Click Close to close the dialog box.
