treams.io.mesh_spheres

treams.io.mesh_spheres(radii, positions, model, meshsize=None, meshsize_boundary=None)

Generate a mesh of multiple spheres.

This function facilitates generating a mesh for a cluster spheres using gmsh. It requires the package gmsh to be installed.

Examples

>>> import gmsh
>>> import treams.io
>>> gmsh.initialize()
>>> gmsh.model.add("spheres")
>>> treams.io.mesh_spheres([1, 2], [[0, 0, 2], [0, 0, -2]], gmsh.model)
<class 'gmsh.model'>
>>> gmsh.write("spheres.msh")  
>>> gmsh.finalize()
Parameters:

  • radii (float, array_like) – Radii of the spheres.

  • positions (float, (N, 3)-array) – Positions of the spheres.

  • model (gmsh.model) – Gmsh model to modify.

  • meshsize (float, optional) – Mesh size, if None a fifth of the largest radius is used.

  • meshsize – Mesh size of the surfaces, if left empty it is set equal to the general mesh size.

Returns:

gmsh.model
