template_sphere_shell¶
- openpnm.topotools.template_sphere_shell(outer_radius, inner_radius=0, dim=3)[source]¶
This method generates an image array of a sphere-shell.
It is useful for passing to Cubic networks as a
template
to make spherical shaped networks.- Parameters
outer_radius (int) – Number of nodes in the outer radius of the sphere.
inner_radius (int) – Number of nodes in the inner radius of the shell. a value of 0 will result in a solid sphere.
dim (scalar) – Controls the number of dimensions of the result. 3 returns a sphere, while 2 returns a disk.
- Returns
im – A Numpy array containing 1’s to demarcate the sphere-shell, and 0’s elsewhere.
- Return type
