Dear Amber users,

When I check how the EWald works in AMBER 6 I just run a trival system,
a water molecule in a big box, 20*20*20
using cutof 9 with sander, just a minimization.

I found the energy ouput , surprised to me that there is even a vwd term.
Doese anyone know how the van der Waals term comes out ?
Also I found the van der Waals term changes with the the cutoff, when
cutoff is smaller, the term becomes big.
