So now let's talk about element quality. Here's an initial mesh from a
structured or grid based mesh generation algorithm. A uniform density
of elements has been used to represent the two layers of material in
this bunny model. The plot on the right of the element quality shows
the volume of the elements on one axis, and the minimum solid angle on
the other. In this initial model all of the elements are too small for
our target tetrahedral count of 10 thousand elements. But we can see
many have very nice shape due to the regular subdivision within each
cell. The target is to move all elements toward the right corner of
the plot.
