I have started simulations with the GROMACS 4.6.1, but I am bit confused
with the application of the vdw-modifier. As far as I understand, in the
case of :
the result will be a LJ potential shifted by a constant in order to be zero
at the cut-off distance. But in the case where:
the Switch function already modifies the potential and the forces in order
to smoothly go to zero between the rvdw-switch and rdvw distances..
What is then the role of the vdw-modifier in the latter case?
Thanks in advance
