`**mesh_sphere_in_cube`#

Description#

This command creates the mesh (1/8) of a cube with a spherical cavity.

Syntax#

**mesh_sphere_in_cube \(~\,\) *ncut_radius nc_r \(~\,\) *ncut_theta nc_t \(~\,\) *size_cube half_edge \(~\,\) *radius_sphere radius \(~\,\) *nb_reg nlayer \(~\,\) [ *quad ]

*ncut_radius: Number of subdivisions along the radius.
*ncut_theta: Number of subdivisions along \(\theta\).
*size_cube: Edge length/2 of the cube.
*radius_sphere: Radius of the sphere.
nb_reg: is the number (integer) of layers with the same hole roundness. It allows a smooth transtion of mesh roundness away from the cavity.
*quad: Quadratic interpolation (by default, it is linear).
