WebIn the worst-case scenario, this can blow particles out of the simulation box. Thus, as a general rule you should not use the fix wall/region command with union or interesect regions that have convex points or edges. The energy of wall-particle interactions depends on the specified style. For style lj93, the energy E is given by the 9/3 potential: WebID, group-ID are documented in fix command; wall/region = style name of this fix command; region-ID = region whose boundary will act as wall; style = lj93 or lj126 or …
