Exporting Meshes or Faceted Geometry

A mesh generated by the Meshing application can be exported into the following file formats:

  • Meshing File format (*.meshdat), suitable for import into Ansys Workbench

  • Ansys Fluent mesh format (*.msh), suitable for import into Ansys Fluent

  • Ansys Polyflow format (*.poly), suitable for import into Ansys Polyflow

  • CGNS format (*.cgns), suitable for import into a CGNS-compatible application

  • Ansys ICEM CFD format (*.prj), suitable for import into Ansys ICEM CFD

  • TGrid Faceted Geometry format (*.tgf), suitable for import into Fluent Meshing (formerly TGrid)

To export a mesh:

  1. Generate the mesh.

  2. If necessary, select an Export Unit or Export Format from the Defaults group in the Details View.

  3. Select File> Export from the main menu.

  4. In the Save As dialog box, choose a directory and specify a file name for the file. Then choose a file type from the Save as type drop-down menu and click Save.

Note:

  • You can also use the Meshing application to export faceted geometry for use in Ansys Fluent Meshing. In such cases you can skip step 1 above. A file with the extension .tgf is created, suitable for import into Ansys Fluent Meshing.

  • When the same entity is a member of more than one Named Selection, those Named Selections are said to be "overlapping". If you are exporting a mesh into the Ansys Fluent, Ansys Polyflow, CGNS, or Ansys ICEM CFD format (or faceted geometry into the Ansys Fluent Meshing format), and overlapping Named Selections are detected, the export will fail and you must resolve the overlapping Named Selections before proceeding. Any Named Selection whose Send to Solver option is set to No is skipped during the check for overlapping entities in Named Selections. For this reason, an easy way to avoid overlapping Named Selections is to set all values of Send to Solver to No. For details, see Repairing Geometry in Overlapping Named Selections.
