Program Zeno can perform four different computations on bodies:

Please, check the box which you would like to compute. 

ZENO computation

Computes the capacitance and polarizability of bodies by the "Zeno" algorithm, and then uses these to estimate transport properties.

INTERIOR computation: 

Computes the volume and radius of gyration of the interior -- by a Monte Carlo integration -- by generating a set of points through the interior.

SURFACE computation: 

Computes she surface area, the radius of gyration of the surface, and the Kirkwood-hydrodynamic radius (i.e., the hydrodynamic radius as evaluated by the Kirkwood double sum approximation) -- by Monte Carlo integration -- by generating surface points.

PROJECT-ONTO-A-LINE computation: 

Computes the Giddings length, LG, which is expected to be predictor of the elution volume in size exclusion chromatography and also computes the mean projection onto a plane
