Preamble:


The RBE3 element, also known as the weighted average constraint element,
provides a means of specifying the value of selected degrees of freedom
to be the weighted average of the displacement of the other degrees of
freedom.

It can be used to good effect in "beaming" loads into a structure without
causing the included region to be over-constrained. It can be used to distribute
a point load onto a set of nodes, as a pressure would behave, and it can be
used to simulate a wiffle tree.
