Having mastered the basic usage of the graphical user in- terface, users are introduced to generating simple meshes on the sphere.
A more complicated three-dimensional annulus is also constructed and meshed, demonstrating some more advanced features of Gmsh. A basic, two-dimensional, geometry is then con- structed within Gmsh and a mesh is constructed. We first define what a mesh is and then intro- duce the reader to the basics of the Gmsh graphical user interface. It is aimed towards complete beginners only some ba- sic knowledge of the Linux terminal and a text editor is assumed.
