I’m trying to simulate TIP4P water without long-range Coulomb interactions. In the archive ( http://lammps.sandia.gov/threads/msg14816.html ), you mentioned that this can be done by placing the charge on the oxygen atom and then shifting it to the M position. As a beginner of LAMMPS, I can’t figure out how this can be carried out in practice. Can you give me some examples, or just tell me where to look at in the manual?
