[gmx-users] monitor energy

[David L. Bostick]

HI..

If I remember correctly .. there is a workaround for finding the long range
contribution for groups that are energy monitored .. something involving
doing a rerun of a trajectory and setting charges equal to zero using
tpbconv.  This way you can monitor total coulomb energy for a group.. check
the archives of the user list on the gromacs website to find out..
