The  Matlab toolbox make it possible to generate mesh files from .geo files by using gmsh. It’s also possible with the ooGmsh2 and ooGmsh4 classes to read the mesh file (respectively for MSH file format version 2.2 and version 4.x) and to store its contains in more user-friendly form. This toolbox must be regarded as a very simple interface between gmsh files and Octave. So you are free to create any data structures or objects you want from an ooGmsh2 object or an ooGmsh4 object.

Here are some examples using ooGmsh2 object:

Graphical representations are done with the fc_graphics4mesh toolbox.

  Matlab / Mesh / fc_oogmsh/ Requirements

This toolbox needs

• gmsh, a three-dimensional finite element mesh generator with built-in pre- and post-processing facilities, to be installed. For automatic detection of gmsh binary, its location suppose to be

  • for Linux and MacOS, in ~/bin/gmsh,

  • for Windows 10, in %HOMEPATH%/Softwares/GMSH/gmsh.exe,

• Matlab (>= 2015b).

  Matlab / Mesh / fc_oogmsh/ Tested on

This toolbox was only tested on Ubuntu 22.04.1 with Matlab R2022a.

  Matlab / Mesh / fc_oogmsh/ Installation

For automatic installation, one has to get/download the install file mfc_oogmsh_install.m Thereafter, one run it under Matlab. This command download, extract and configure the fc-oogmsh toolbox and all the required toolboxes in the current directory.

By default, the gmsh binary is supposed to be located in

• <USERDIR>/bin/gmsh under linux and MacOS,

• <USERDIR>/Softwares/GMSH/gmsh.exe under Windows.

To specify an other location one can do

>> mfc_oogmsh_install(’gmsh_bin’, GMSH)

>> fc_oogmsh.configure(’gmsh_bin’,’~/gmsh-4.11.0/bin/gmsh’)

For example, to install this toolbox in ~/Matlab directory, one have to copy the file mfc_oogmsh_install.m in the ~/Matlab directory. Then in a Matlab terminal run the following commands

>> cd ~/Matlab 
>> mfc_oogmsh_install

There is the output of the mfc_oogmsh_install command on a Linux computer:
