From: eap For a triangle
- 2D element consisting of 3 nodes a the Aspect
- Ratio 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 3(1/2) /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 Aspect
- Ratio for the element. where : For a quadrangle
2D element consisting of 4 nodes the
- Aspect Ratio is the ratio of the
- element's longest side to its shortest side.
+ 2D element consisting of 3 nodes the Aspect
+ Ratio is calculated by formula:

-
+ Aspect Ratio is the
+ quality of the worst triange which can be built taking three nodes of
+ the quadrangle. There are four triangles to consider:
