9th International Meshing Roundtable
October 2-5, 2000, New Orlean Louisiana
Fluent, lnc., 500 Davis St. Suite 600, Evanston, IL, U.S.A.
One of the original founders of the Sandia CUBIT meshing research
group and the International Meshing Roundtable, Dr. Blacker has
been an active researcher in mesh generation for many years. He
developed the paving algorithm for quadrilateral meshing and has
made significant contributions with various hexahedral meshing
algorithms. He graduated from Brigham Young University in 1983
with a Masters in Civil Engineering, and later obtained a Ph.D.
in Theoretical and Applied Mechanics from Northwestern University.
He is currently employed by Fluent and is responsible for the
Gambit software product, a preprocessor tool for geometry and
mesh generation for the Fluent suite of analysis tools. Dr. Blacker
will speak about hexahedral mesh generation; its history, the state
of the art, and some musings about the future of this research
area with a particular emphasis on the practical application
of the various techniques.
Automated hexahedral element meshing has been the "Holy Grail" of
mesh generation research for years. The rigid connectivity and
shape constraints of these meshes provide the challenge. The
ever-present economic pressure for automating meshing of complex
geometries, difficult transitions and large mesh sizes establishes
the opportunity. This paper will systematically review the
requirements of the hexahedral meshing challenge, the various
approaches to the solution of the problem (along with their
respective attributes), and some musings about future research
