Dear Xueming: the word "mol" is short form for "mole" http://en.wikipedia.org/wiki/Mole_%28unit%29 In the pull code context, it refers to moles of the pulled group. The force is not "applied" to the COM of a cluster. The magnitude of the force is determined based on the COM distance, and the

Hi there The units for pull_k1 = $$ kJ/mol/nm. If this force is applied to a cluster, the "/mol" in the units of force means per atom in the cluster, or single molecule composed of several atoms? Sorry, I don't know the default value of mol in gromacs. Does that mean per molecule? Besides, the for
