Webcommand, or when the fix wall/region command uses a region surface as a bounding wall on particle motion, i.e. a rotating container. The {delete} style removes the named region. Since there is little overhead to defining extra regions, there is normally no need to do this, unless you are defining and discarding large numbers of regions WebA reflecting wall should not be used with rigid bodies such as those defined by a “fix rigid” command. This is because the wall/reflect displaces atoms directly rather than exerts a force on them.
