4.14.12 Fieldview Unstructured Files

Select Fieldview Unstructured from the File Type drop-down list and select the scalars you want to write in the Quantities list. Click the Write... button to save the file for the specified function(s), using the Select File dialog box.

The following files are written:

• A binary file (e.g., file.fvuns) containing coordinate and connectivity information and specified scalar function data.

• A regions file (e.g., file.fvuns.fvreg) containing information about the cell zones and the frame of reference.

The cell zone information includes the names of the cell zones along with the mesh numbers. For the rotating frame of reference, the regions file contains information about the origin, the axis of rotation and the rotation speed. Volume data is written using the absolute frame of reference.

If you are running multiple steady-state solutions on the same mesh, you can export only the data files and avoid the repeated writing of the mesh file by using the following TUI command:

file/export/fieldview-unstruct-data file_name list_of_scalars q

where

• file_name specifies the name (without the extension) of the file that you wish to write.

• list_of_scalars specifies the list of cell functions (separated by spaces, i.e., no commas) that you want to write to the exported file. The q input terminates the list. For example, the input x-velocity cell-zone q will select $x$ velocity and the cell volume.

ANSYS FLUENT allows you to export polyhedral data to FIELDVIEW. Note that while FIELDVIEW supports postprocessing of meshes with polyhedral cells, the polyhedra will be decomposed into tetrahedral cells. This is a limitation of FIELDVIEW.

You have the option of exporting data at specified intervals during a transient calculation through the Automatic Export dialog box. See Section  4.16 for the complete details.
