Dear justin Thank you for your previous reply

I have solvated my protein molecule with specific number of water molecules By keeping the protein (solute) at center of box (option available in editconf) but when i visualize the resultant .gro file in VMD the solute molecule are not closely surrounded by water molecules i need Solute molecules to be closely surrounded by solvent molecules without changing the dimension of box i am using Cubic box is there is any option in available in gromacs

No - genbox works by tiling the given solvent coordinate file into the solute coordinate file starting at the coordinate origin. You could randomly insert individual water molecules with -ci -nmol, but you'll still end up with significant voids akin to the gas phase, or more likely something that doesn't even make sense.
