ABSTRACT
In general, the higher the quality of the elements of a mesh
(triangulation) the better it is for solving an application problem
modeled by this mesh. A number of geometric algorithms and software
have been developed over the last two decades for computing graded
meshes with guaranteed quality. However, these methods tend to fail
catastrophically when the mesh elements are expected to be very high
quality (e.g., all angles larger than 40 degrees and/or all angles
strictly less than 90 degrees). We present new algorithms and software
for computing premium quality graded meshes.
BIOGRAPHY
Alper Ungor obtained his Ph.D. degree in Computer Science from the
University of Illinois at Urbana-Champaign in 2002. After spending two
years at Duke University as a postdoc, he joined the University of
Florida where he is currently an Assistant Professor of Computer and
Information Science and Engineering. Alper is the recipient of the
2002 David Kuck Best Ph.D. Thesis Award at the University of Illinois.
He also received a CAREER Award from the National Science Foundation in
2009. His research and teaching interests include the design and
analysis of algorithms, computational geometry, mesh generation,
scientific computing, and computational biology.
