Hi all gromacs users Several days ago I wrote a letter to Gromacs mailing list about virial calculation and Berk gave me some suggestions. I sum the virial in the inner loop but I don't know how to determine the contribution of the angle and dihedral forces to the virial. I read the discussion about virial on the mailing list archive, but most of the discussion is about "single sum virial" used in Gromacs. So can someone explain how to calculate the angle and dihedral force virial? Or give me some papers about suming the virial?
Appreciate any help in advance! Best wishes! xuji [EMAIL PROTECTED] 2008-12-02
