2D element consisting of 3 nodes a the <span style="font-weight: bold;"><B>Aspect
Ratio</B></span> is calculated as the ratio of the length, h2, of the edge
of this triangle, to the height, h1. The ratio of h2 to h1 is then multiplied
by &nbsp;3<span
style="vertical-align: Super; font-size: 10pt;"><font size=2 style="font-size:10pt;">(1/2)</font></span> /2, so that
a “perfect” element in the shape of an equilateral triangle will be equal
to 1. This procedure is repeated for the remaining two edges of the triangle,
and the largest value is retained as the <span style="font-weight: bold;"><B>Aspect
Ratio</B></span> for the element.</p></li>
