creating mesh from geo file in gmsh using matlab?

Hello All,

I am trying to create a mesh file from a geo file that is created by MATLAB. Can I directly call gmsh and do meshing through some command in MATLAB?

I have seen few examples but not so clear. It will be great if someone can help me to do the meshing. I have attached my geo file. Its a txt version.

Thanking you in advance, km

If the .geo file is valid you should be able to mesh it in Gmsh directly (or use a system call from Matlab like is done in the FEATool toobox).

In Matlab, you can send the geo file to Gmsh via some operating system command.

In Im2mesh (an open-source Matlab package), I demostrate how to define 2d geometry in Matlab and then generate mesh with Gmsh.

Please check these two examples: demo14 demo13

To run demo14, you need to install Matlab mapping toolbox, and download Im2mesh package and Gmsh sofware.
