dear all,
I want to simulate water with tip4p model with long-range Coulombic solver for big simulation box.
my ensemble is nvt. but system gives error.
ERROR: Out of range atoms - cannot compute PPPM (…/pppm_tip4p.cpp:107)
pppm/tip4p can not compute it. size of my simulation box is (1001005)
unit is real.
how to use ewald for tip4p water model ?
thanks a lot.
