The oblate hard spherocylinder model [1], also known as a discotic spherocylinder, consists of an impenetrable cylinder, surrounded by a torus whose major radius is equal to the radius of the cylinder, and whose minor radius is equal to half of the height of the cylinder. In the limit of zero diameter the oblate hard spherocylinder becomes a hard sphere, and in the limit of zero width one has the hard disk. A closely related model is that of the hard spherocylinder.
Overlap algorithm
