Note that you should not make the lo/hi values radically smaller/larger than the extent of the atoms. For example, if your atoms extend from 0 to 50, you should not specify the box - bounds as -10000 and 10000 unless you also use the :doc:`processor - command `. This is because LAMMPS uses the specified box + bounds as -10000 and 10000 unless you also use the :doc:`processors + command `. This is because LAMMPS uses the specified box size to layout the 3d grid of processors. A huge (mostly empty) box will be sub-optimal for performance when using "fixed" boundary conditions (see the :doc:`boundary ` command). When using
