Karol Brzezinski proposed the following answer:
Hi Ahmad,

could you provide the MWE (Minimum Working Example)[1] that shows the
difference that you are talking about?

1 - aabbDim() computes dimensions of a minimum axis aligned bounding box containing all the spheres from the simulation.
2 - triax.boxvolume probably computes volume from periodic cell dimensions.

There are multiple reasons to get different results (e.g using non-
spherical particles in the simulation, the cell is not fully filled with
spheres, particles are 'outside' the cell, etc.).

Cheers,
Karol
