4. Use

PRE_GMSH can read GMSH files in ASCII 1.0 and 2.0 formats.

Note

GMSH can read and write meshes in MED format. The MED format is therefore preferred.

In GMSH, entities are numbered and sometimes named. When proofread by PRE_GMSH, only the numbers are retained.

All groups of elements with numbers 1, 2,… created in GMSH (« physical ») are transformed into mesh groups (GROUP_MA) with the name GM1, GM2,… created in (« physical ») are transformed into mesh groups () with the name,,…

At the astk interface level, the mesh file produced by GMSH (which gives it the extension.msh) is re-read by PRE_GMSH on the logical unit 19 by default.

The generic type for geometry data is.datg (logical unit 16 by default).
