-- The <b>Aspect Ratio</b> of a \b quadrangle 2D element consisting of
- 4 nodes is the worst (i.e. the greatest) value from all triangles
- which can be built taking three nodes of the quadrangle. There are
- four triangles to consider:
+- The <b>Aspect Ratio</b> of a \b quadrangle 2D element consisting of 4
+nodes is calculated using The Verdict Geometric Quality Library
+available within VTK. The calculation formula is:
