Skewness is one of the primary quality measures for a mesh. Skewness determines how close to ideal
(i.e., equilateral or equiangular) a face or cell is.
According to the definition of skewness, a value of 0 indicates an equilateral cell (best) and a value of
1 indicates a completely degenerate cell (worst). Degenerate cells (slivers) are characterized by nodes
that are nearly coplanar (colinear in 2D).
Highly skewed faces and cells are unacceptable because the equations being solved assume that the
cells are relatively equilateral/equiangular.
