Description

IMPEXP_GMSH Import/export grid in GMSH format.

[ GRID ] = IMPEXP_GMSH( FILE_NAME, MODE, DATA, IIND, FID_LOG, BIX ) Import and export of Gmsh (.msh) Ascii mesh and grid file format.

FILE_NAME is a string specifying the (root) file name to process.

MODE can either be a string indicating IMPORT (where boundary numbering are reconstructed from Gmsh physical or elemental tags if available), IMPORT_BDR (boundary reconstruction with gridbdr), or EXPORT.

With the (default) IMPORT mode option the function returns a GRID struct. While for export, the input DATA can be given as either a valid fea finite element data struct, or a FEATool grid struct.

IIND is an optional array for physical domains (subdomains in 2D and boundaries in 3D) to extract and import (default all).

FID_LOG is an optional log file handle for message output (negative for Gui output or empty for no output).

BIX is an optional index vector to correct boundary numbering. Alternatively, BIX = 0/false disables boundary reconstruction during import.
