Crate rgmsh

Unofficial, opinionated Rust bindings for the Gmsh API.

From the Gmsh website:

Gmsh is a free 3D finite element mesh generator with a built-in CAD engine and post-processor.

Gmsh is copyright (C) 1997-2019 by C. Geuzaine and J.-F. Remacle

The full Gmsh reference manual is available at: http://gmsh.info/doc/texinfo/gmsh.html

The Gmsh API

Gmsh has four main modules:

1. Geometry
2. Mesh
3. Solvers
4. Post-processing

Rust API design

Gmsh uses tags to keep track of different components. For example, adding a point to a geometry model will return a PointTag.

Tags are used everywhere in Gmsh, not just for geometry. Other examples are:

• Mesh elements,
• Post-processing data sets,
• Mesh refinement fields.
