This paper explores potential methods for characterizing the meshing complexity of
solid geometry. While numerous metrics exist to measure the quality of the finite
element, there are currently no metrics that measure the quality of a solid with
respect to its meshing complexity. The meshing complexity of a solid is defined by
how difficult it is to generate a valid finite element mesh for a given solid.
There are many variables that affect meshing complexity. This paper seeks to
discuss methods that are decoupled from more subjective variables such as user
expertise and software maturity, and it will focus on methods that describe the
topological and geometric aspects of a solid. It will present techniques based on:
medial axis transformation, wavelets, curvature, proximity, intersection, heuristic
topology search, and the measurement of space (volume/area/length) and will
analyze their suitability as meshing complexity metrics.
