Delaunay Criterion Violations
Unit: [-]
A triangular finite element violates the Delaunay
criterion if the circumcircle of the triangle includes a node not belonging
to the finite element. Delaunay-compliant triangulations maximize the
minimum angle of all the triangles in the mesh, elements with large angles
that are potentially leading to instabilities are avoided.
Elements violating the criterion get a value of 1 in this parameter, triangles
being consistent with the criterion have a value of 0. In the default
color scheme and legend setting, triangles with a violation of the criterion
are shown in red.
