Re: [Question #691255]: voxelPorosity

 

Question #691255 on Yade changed:
https://answers.launchpad.net/yade/+question/691255

Jan Stránský proposed the following answer:
sorry, I misinterpreted your question..
V is the total cube voluem
Vv is the approximation (based on the voxelization) of the volume occupied by spheres
Regardless any cone or other bodies..

The second part of my answer concerning "proper porosity" still holds
and is quite elegant.

Another point, do you have significant overlaps / overlaps of more than
two particles at a time? If no, You can compute porosity more simply as
the sum of volume of individual spheres. Voxel porosity is relatively
rough approximation, applicably (IMO) mainly for hugely overlapping
spheres e.g. composing a arbitrary-shaped clump.

cheers
Jan
