	<~~!ELEMENT~~ load (~~#PCDATA~~)>		If needed, particle load boundary conditions can be explicitly assigned to numbered particles by using <tt><load></tt> elements within the single <tt><LoadBCs></tt> element. This approach can only be used in <tt>XML</tt> input files and is rarely used, except perhaps in separate software or scripts that create an <tt>XML</tt> input file automatically. The more common way it to assign [[Particle-Based Boundary Conditions\|boundary conditions to a block of particles]] suing shapes.
