Panel Discussion Notes
October 13, 1999

Format:

Five (5) panelists, listed below, gave summaries of the Birds of a Feather (BOF) discussions held on Monday, which they lead. They also gave their own views on their subject area. The moderator summarized these views, then opened the floor for questions and discussion. The discussion and questions portion was lively, without much need for the moderator to "coerce" participation from the audience.

Panelists:

Moderator: Tim Tautges, Sandia National Laboratories

Panelist summaries:

TRI/TET ALGORITHMS

(David Marcum, Mississippi State U.)

Geometry/surface mesh problems

Dynamic meshes

Geometry definition

STRUCTURED GRID GENERATION ISSUES

(John Steinbrenner, Pointwise)

HEX MESHING

(David White, SNL)

What to look for?

In summary:

DISCUSSION ISSUES

Mesh quality: need a forum for quality metrics from analysis community

Adaptive remeshing may not be possible because of size, or because initial geometry wasn,t captured well enough

Also, haven't thought about modeling errors, e.g. fidelity to original geometry

What are "acceptable" quality metric values?

Question: can mesh generators help geometry modelers?
