spheres_and_cylinders#

spheres_and_cylinders(network, pore_diameter='pore.diameter', throat_diameter='throat.diameter', throat_centroid='throat.centroid')[source]#

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
