GMSH file format for unstructured grids

GMSH is a format for unstructured grids that can contain comments and additional information (“tags”) for the nodesand elements.

We strongly encourage users to include all the following in their GMSH grids:

  • Node list (mandatory)
  • Element list (mandatory), including :
    1. boundary point elements (type 15): not mandatory but very useful to define the open boundary
    2. list of triangle elements (mandatory)
