According to the reference of compute pressure command (Thompson et al. 2009), the virial term could be calculated with eq.25 (the atom form:
in which the "F'in is not the total force on an atom but rather the partial force". But, I could not see in the corresponding section of manual mentioning that the forces are "partial". (W=sum_i(r_i.f_i) [i=1:N')]
could anyone explain this discrepancy for me please?
thank you in advance for your time
