Detailed Description

Implement the interface between TPZGeoMesh and the files produced by Gmsh (version 3.0 or 4.0 ) in msh format.

Since: January 16, 2017 What is Gmsh ? Take a look on http://gmsh.info/ Gmsh is a free 3D finite element grid generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmsh's own scripting language. Note about the implementation for file format 4 The mandatory sections are considered MeshFormat, Entities, Nodes and Elements. The optional section PhysicalName is considered the others (PartitionedEntities,Periodic,GhostElements,NodeData,ElementData,ElementNodeData) are just ignored. To conclude a successful read of your *.msh file, you should have physical tags to be able to insert elements into a TPZGeoMesh object.
