GmshSTL.gmsh_mesh_stl Method

gmsh_mesh_stl(F, V, algorithm3d, min_length, max_length,
              optimize_netgen, quality, msh_version,
              angle_tol, verbosity, output_path)

Create a 3D volumetric mesh from a surface mesh (F, V) using Gmsh and save it to output_path.

Arguments

• F: face connectivity, triangles indexing into V

• V: vertex coordinates, points in 3D

• algorithm3d: Gmsh 3D meshing algorithm:

  • 1: Delaunay

  • 4: Frontal

  • 7: MMG3D

• min_length: minimum characteristic mesh size

• max_length: maximum characteristic mesh size

• optimize_netgen: enable Netgen optimization:

  • 0: off

  • 1: on

• quality: Gmsh mesh quality metric type, usually 2

• msh_version: output .msh version, for example 2.2 or 4.1

• angle_tol: tolerance for detecting overlapping facets

• verbosity: Gmsh verbosity level

• output_path: path to save the generated mesh file

Notes

• (F, V) must define a closed watertight surface.

• The surface is internally written to a temporary STL file.

• A tetrahedral 3D mesh is generated inside the enclosed volume.
