A comparative numerical study of meshing functionals for variational mesh adaptation [PDF]

open access: yes, 2015
We present a comparative numerical study for three functionals used for variational mesh adaptation. One of them is a generalisation of Winslow's variable diffusion functional while the others are based on equidistribution and alignment.

Performance of a streaming mesh refinement algorithm. [PDF]

open access: yes, 2004
In SAND report 2004-1617, we outline a method for edge-based tetrahedral subdivision that does not rely on saving state or communication to produce compatible tetrahedralizations. This report analyzes the performance of the technique by characterizing (a) mesh quality, (b) execution time, and (c) traits of the algorithm that could affect quality or ...
