	Finally, note that if no <tt>ToArchive</tt> command is used, ~~only minimal information is archived (''e~~.~~g.''~~, ~~particle positions). You~~ will ~~need some~~ <tt>ToArchive</tt> commands to ~~be able to later~~ visualize ~~calculations results~~.		Finally, note that if no <tt>ToArchive</tt> command is used, the simulation will archive velocity, stress, strain, and all above "standard" properties. If <tt>ToArchive</tt> commands are used, the velocity, stress, and strain will no longer be archived unless you include them in the <tt>ToArchive</tt> commands along with any other properties you would like to visualize.
