Some of the tools in this section can assist in this process. The fix_modify energy option is supported by this fix to add the energy of interaction between atoms and the wall to the system's potential energy as part of thermodynamic output. 5 Individual commands This section lists all LAMMPS commands alphabetically, with a separate listing below of styles within certain commands. 50 lines (33. Find file Copy path Fetching contributors… Cannot retrieve contributors at this time. In the LAMMPS distribution, the SPH is distributed as an add-on module, which means that it is not by default compiled with the rest of LAMMPS. The analalog for an energy minimization is the fix box/relax command. but after I install what you have suggested I tried to insert the command Make fix_wall_lj126. html # comm): line fix wall / lj93 command: h3 fix wall / lj126 command: h3 fix wall / colloid command: h3 fix wall / harmonic command: h3 [Syntax:] fix ID group-ID style face.
