“ERROR: Illegal fix nvt/npt/nph command”
I built a PE chain by using Polymer Modeler. It seems working well, however, the follwing error occurs “ERROR: Illegal fix nvt/npt/nph command” when you run LAMMPS with the input scripts from Polymer Modeler. It seems Polymer Modeler does not consider the new patch for LAMMPS. The syntax in LAMMPS changed from 7Apr10.
