2.12.1 FLUENT File Naming in Workbench

When running under Workbench, FLUENT automatically saves the settings, case, and data files for your system as needed.

FLUENT names these files using the base name of the mesh file. If a mesh (or case) file is imported, the base name of the imported file is used as the base name for the settings, case, and data files. If the mesh is created in Workbench, the mesh file uses the system's directory name as its base name.

When FLUENT saves a case file, it appends the base name with the run number. When FLUENT next writes a case file, the run number is incremented in order to avoid overwriting the previous case file. When FLUENT saves a data file, it appends the base name with the same run number as the associated case file and with the iteration (or time-step) number at which it was saved. A new case file is not written every time that a data file is written. The case file is only written when the settings and/or mesh is changed.

The following example shows how file naming works in FLUENT under Workbench. In this example, you have a single Fluid Flow (FLUENT) analysis system and you have created the mesh in Workbench.

1.   Double-click on Setup cell. FLUENT launches and loads FFF.msh.

2.   In ANSYS FLUENT, specify boundary conditions, initialize the solution and enter 10 iterations on the Run Calculation task page.

3.   In the FLUENT application, select the Calculate button.

FFF.set file is written and 10 iterations are completed.

4.   Save the project.

FFF-1.cas.gz and FFF-1-00010.dat.gz are written.

5.   In the FLUENT application, select the Calculate button.

10 additional iterations are completed.

6.   Save the project.

FFF-1-00020.dat.gz is written.

7.   In the FLUENT application, change the value of the inlet velocity, select the Calculate button. When prompted, select the Store the modified settings for a future calculation and use them this time option.

FFF.set is written (overwriting the existing file) and 10 additional iterations are completed.

8.   Save the project.

FFF-2.cas.gz and FFF-2-00030.dat.gz are written.

The same naming convention is used when autosaving with FLUENT under Workbench.
