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 :
- boundary point elements (type 15): not mandatory but very useful to define the open boundary
- list of triangle elements (mandatory)
