Description
q=pdetriq(p,t)
returns a triangle quality measure given mesh data.
The triangular mesh is given by the mesh data p
, e
, and t
. For details on the mesh data representation, see initmesh
.
The triangle quality is given by the formula
where a is the area and h1, h2, and h3 the side lengths of the triangle.
If q > 0.6 the triangle is of acceptable quality. q = 1 when h1 = h2 = h3.
