spheres_and_cylinders

spheres_and_cylinders(network, pore_diameter='pore.diameter', throat_diameter='throat.diameter', throat_centroid='throat.centroid')

Computes the endpoints of throats when pores are spherical.

The endpoints lie inside the sphere, defined by the lens formed between the intersection of the sphere and cylinder.

Parameters:

network (OpenPNM Network object)

pore_diameterstr

Name of the dictionary key on network containing the ndarray of pore diameter values.

throat_diameterstr

Name of the dictionary key on network containing the ndarray of throat diameter values.

throat_centroidstr

Name of the dictionary key on network containing the ndarray of throat centroid coordinate values.

Returns:

endpoints – An array containing the Nt-2-3 coordinates of the end points of each throat.

Return type:

ndarray
