Re: PME & cutoff

Dear Hungie
The cutoff is applied to the van der Waals interactions. A correction for
the energy and pressure is also added. The electrostatics is not cutoff.
the "direct sum" is cutoff, but the "reciprocal sum" approximated by pme,
compensates for what is missing in direct sum
Hope this helps
