Importing and exporting meshes

In MESH there is a functionality allowing import/export of meshes from/to MED, UNV (I-DEAS 10), DAT (simple ascii format), STL, GMF (internal format of DISTENE products, namely MG-CADSurf, MG-Tetra and MG-Hexa algorithms) and CGNS format files. You can also export a group as a whole mesh.

To import a mesh:

  1. From the File menu choose the Import item, from its sub-menu select the corresponding format (MED, UNV, STL, GMF and CGNS) of the file containing your mesh.
  2. In the standard Search File dialog box find the file for import. It is possible to select multiple files to be imported all at once.
  3. Click the OK button.

To export a mesh or a group:

  1. Select the object you wish to export.
  2. From the File menu choose the Export item, from its sub-menu select the format (MED, UNV, DAT, STL, GMF and CGNS) of the file which will contain your exported mesh.
  3. In the standard Search File select a location for the exported file and enter its name.
  4. Click the OK button.

If you try to export a group, the warning will be shown:

There are additional parameters available at export to MED and SAUV format files.

Auto Groups

  • Automatically create groups check-box specifies whether to create groups of all mesh entities of available dimensions or not. The created groups have names like “Group_On_All_Nodes”, “Group_On_All_Faces”, etc. A default state of this check-box can be set in Automatically create groups for MED export.

  • Automatically define space dimension check-box specifies whether to define space dimension for export by mesh configuration or not. Usually the mesh is exported as a mesh in 3D space, just as it is in Mesh module. The mesh can be exported as a mesh of a lower dimension in the following cases, provided that this check-box is checked:
    • 1D: if all mesh nodes lie on OX coordinate axis.
    • 2D: if all mesh nodes lie in XOY coordinate plane.
