ogstools.meshlib.gmsh_meshing.remesh_with_triangles(mesh, output_file=Path() / 'tri_mesh.msh', size_factor=1.0, order=1)[source]#

Discretizes a given Mesh with triangles and saves as gmsh .msh.

Requires the mesh to be 2D and to contain ‘MaterialIDs in the cell data.

Parameters:

  • mesh (UnstructuredGrid) – The mesh which shall be discretized with triangles

  • output_file (Path | str) – The full filepath to the resulting file

  • size_factor (float) – A factor to scale the element sizes.

  • order (int) – The element order (1=linear, 2=quadratic, …)
