Multiple throats might overlap in the same location causing overestimation of porosity

[avez1999]

Hi,
I’m working with a cubic unit cell containing 8 pores (nodes) and 28 cylindrical throats (edges), each defined by a pore radius and throat radius.

I’ve noticed that multiple throats can geometrically overlap (especially near corners or diagonals), which leads to an overestimation of porosity when I compute the total pore + throat volume directly.

Is there a function or recommended approach in this library to:

detect and handle throat–throat (or multi-throat) overlaps based on input throat-dia and network, or

subtract shared volumes between intersecting throats?

Thanks for the help.
