[gmx-users] macromolecule in solution

[ARGYRIOS KARATRANTOS]

for a macromolecule in solution do I have to use exactly what gromacs says, that
in any direction of the box, the box size must be: size of macromolecule +
2*Rcutoff?

if I applied that in a long macromolecule chain I can not have the desirable
mass fraction (Wpolymer=0.2)
