In MESH there is a functionality allowing import/export of meshes in the following formats:
* **MED**,
-* **SAUV** (format of the CASTEM code),
* **UNV** (I-DEAS 10),
* **STL**,
* **CGNS**,
Only MED format supports all types of elements that can be created in the module. If you export a mesh or group that includes elements of types that are not supported by chosen format, you will be warned about that.
-There are additional parameters available at export to MED and SAUV format files.
+There are additional parameters available at export to MED format files.
