EDEM Voidage is the percentage of space not taken up by particles. Voidage can be obtained by creating a Grid Bin and Creating a Voidage query. The Voidage property is calculated as:

Voidage therefore does not consider the overlap between particles, which this quantifies the deformation of the particles. A particle which overlaps two or more bins will only be counted in the bin that contains the particle center of mass.

EDEMpy Porosity consider the overlap between particles and be counted in the bin that contains the particle volume, Radius, mass and overlap distance etc…
