compute group/group in a different model

Thanks your reply!
The question is that if the thermo output is divided extensive quantities by N,then how to get the extensive quantities and which atoms of group need to be multiplied? because the two groups which were computed are not similar.

All the thermo output is doing for extensive vs intensive
is dividing by N = total # of atoms. Thermo output knows
nothing about groups or the size of groups. You can undo or do
the factor of N yourself in many ways.
