I don't know what time it is you want to decrease. Solvateshell creates just
a sphere of water molecules about some point. It is not very accurate, since
the polarization of waters outside the "shell" is not accounted for, and there
can be unphysical effects at the water-vacuum boundary at the edge of the
water shell.
Solvateshell cannot be used for periodic simulations; use solvateBox or
solvateOct for that purpose.
...good luck...dac
