FUN3D supports only 3D structured and unstructured export. Data is exported as binary in double precision. Volume conditions are not supported. The FUN3D plugin was developed and provided by NASA Langley Research Center.

FUN3D Options
The Export CAE panel for the NASA/FUN3D Solver.

The Mesh Link frame provides options to indicate whether you wish to write out the Mesh Link and Database files during the export process in *.xml and *.nmb formats respectively. Furthermore, the Database file can be exported in either Binary (default) or ASCII format. For more information on the Mesh Link format and libraries, please visit our GitHub page:

The Database file contains all the database entities that have grid entities constrained to them. On the other hand, the Mesh Link file contains link information between the grid entities being exported and the database entities in the Database file. Checking on the Export Mesh Link and Database files options will run the Mesh Link process and export these two additional files.

When Export Mesh Link and Database files options is checked on, the Mesh Link and Database file browser buttons become enabled. These buttons will open up a file browser dialog window that will allow you to independently chose the location of the exported Mesh Link and Database files. Note that the text fields for both files are read-only; these fields will be populated with the base name selected for CAE export.
