I would like to use tip4p/ice water potential which is a modified version of tip4p. I see that lj/cut/coul/long/tip4p pair style will be included as a patch in the near future. Could you give an approximate time frame of when it will happen?
Also, does anyone know how one can alternatively implement tip4p potential using standard pair styles (i.e. lj/cut/coul/long)? Assigning LJ parameters for oxygen and hydrogens, and placing the positive charges on the hydrogens and the negative on the 4th tip4p site did not work for me. The system blew up immediately, probably due to the 4th site being massless.
