In my simulation box including 2 immiscible fluids I need to find the volume of each fluid. I would be appreciated if I have your advice. using thermo_style we have volume of the entire of the system not an specific group/

determining the volume of a group of atoms is a recurring question in

this mailing list.

you may want to search for previous discussions on the subject.

it cannot be computed exactly, as the exact extent of a single

particle is an ill-defined property on the atomic scale.

what can be done is to take the cell volume and come up with some way

to partition it, e.g. use the average volume of a particle in bulk or

use some strategy like voronoi tesselation.

if your system is a periodic system without any walls or vacuum

regions, voronoi tesselation seems like a viable option, but since

your description is too vague, it is impossible to give a more

specific suggestion.
