Hello everyone,
I want to normalize the energy by compute group/group command.
Let’s say we have a system containing 1000 H2O molecules(group 1) and 500 CO2(group 2) molecules.
The compute group/group commands are
compute ge11 1 group/group 1 pair yes kspace yes
compute ge12 1 group/group 2 pair yes kspace yes
compute ge22 2 group/group 2 pair yes kspace yes
If I want to normalize the energy on each pair(H2O-H2O,H2O-CO2,CO2-CO2), should I divide group energy by the number of pair?
That is
for per H2O-H2O, the energy is ge11/(10001000)
for per H2O-CO2, the energy is ge12/(1000500)
for per H2O-H2O, the energy is ge22/(500*500)
Am I correct here?
Thank you.
