/*
|
|
* Mesh quality metric functions that compute the aspect frobenius of certain mesh cells.
|
|
* The aspect frobenius metric generally measures the degree of regularity of a cell, with
|
|
* a value of 1 representing a regular cell..
|
|
** These metric computations are adapted from the VTK implementation of the Verdict library,
|
|
* which provides a set of mesh/cell metrics for evaluating the geometric qualities of regions
|
|
* of mesh spaces.
|
|
** See: The Verdict Library Reference Manual (for per-cell-type metric formulae)
|
|
* See: vtk/ThirdParty/verdict/vtkverdict (for VTK code implementation of this metric)
