The  Octave package 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 package 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.

  Octave / Mesh / fc_oogmsh/ Installation

For automatic installation, one has to get/download the install file ofc_oogmsh_install.m Thereafter, one run it under Octave. This command download, extract and configure the fc-oogmsh toolbox and and all the required packages 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 10

It can be directly given by using the ’gmsh_bin’ option of the install command :

For example, to install this package in ~/Octave directory, one have to copy the file ofc_oogmsh_install.m in the ~/Octave directory. Then in a Octave terminal run the following commands

There is the output of the ofc_oogmsh_install command :

The complete toolbox (i.e. with all the other needed packages) is stored in the directory

If it’s the first time the fc_oogmsh.init() function is used, then its output is

For uninstalling, one just has to delete directory :
