GMSH Samples

A few samples of Gmsh meshes and geometries for using with Finite Volume solvers.

Installing GMSH

To open those samples, you need to have a Gmsh binary.

• For standalone binaries (Windows included), go to Gmsh's website, extract them and run.
• For Debian-based Linux distributions, use apt-get install gmsh. Notice that this may not give you the latest binaries. If you want those, download from the official website.

Running

If you already have Gmsh installed, you can follow those steps to run the software:

• From Windows, just run gmsh.exe
• From Linux, if you have installed from the repository, you can run $ gmsh from the terminal.
• From Linux, if you have downloaded the binaries, go to the extracted folder and run $ ./gmsh. To open a given mesh, you can use the contextual menu File -> Open, or if you're using a terminal, you can pass the mesh/geometry file as argument to gmsh (for example, $ gmsh mesh1.msh).

Interface with MATLAB

This project also includes an interface with MATLAB through the file load_gmsh.m. This file includes a function, called load_gmsh, that takes a filename as argument, and returns a struct object containing mesh-related fields (points, elements, ...). Example of usage:

m = load_gmsh('Geometria1.msh');
