Dune-Gmsh4

File reader for the Gmsh MSH file format version 4.

Summary

Provides a file reader to read MSH file format version 4. It supports various grid-creator policies. Higher-order parametrized grids can be read using a LagrangeGridCreator.

Installation Instructions

dune-gmsh4 requires the DUNE core modules, version 2.9 or later. Please see the general instructions for building DUNE modules for detailed instructions on how to build the module.

Usage

Either construct a grid directly

#include <dune/gmsh4/gmsh4reader.hh>
#include <dune/grid/uggrid.hh>

int main()
{
  using namespace Dune;
  using Grid = UGGrid<2>;
  std::unique_ptr grid = Gmsh4Reader<Grid>::createGridFromFile("filename.msh");
}

or explicitly use a grid-creator

#include <dune/foamgrid/foamgrid.hh>
#include <dune/gmsh4/gmsh4reader.hh>
#include <dune/gmsh4/gridcreators/lagrangegridcreator.hh>

int main()
{
  using namespace Dune;
  using Grid = FoamGrid<2,3>;
  GridFactory<Grid> factory;
  Gmsh4::LagrangeGridCreator creator{factory};
  Gmsh4Reader reader{creator};

  reader.read("filename.msh");
  auto grid = factory.createGrid();
}

Note, the grid-creator itself is a grid-function.
