mesh3d_from_stl

formatwriter.mesh3d_from_stl(output_dir: str, output_prefix: str, max_mesh_size: float = 5.0, min_mesh_size: float = 2.5, export_vtk: bool = True, save_centroids: bool = False)

Generates a 3D FE mesh using linear tetrahedrons from a 3D .stl file using the GMSH library. It is saved in a .dat file. Returns two arrays containing node coordinates and element connectivity, respectively.

Parameters:

• max_mesh_size (float) – Maximum and minimum size for the elements

• min_mesh_size (float) – Maximum and minimum size for the elements

• output_prefix (string) – Prefix for output files

• output_dir (string) – Destination folder

• export_vtk (boolean) – If True exports the mesh as a .vtk file

• save_centroids (boolean) – If True saves the element centroids coordinates as a .csv file.
