S. Dey et al., ELIMINATION OF THE ADVERSE-EFFECTS OF SMALL MODEL FEATURES BY THE LOCAL MODIFICATION OF AUTOMATICALLY GENERATED MESHES, Engineering with computers, 13(3), 1997, pp. 134-152
Issues related to the automated identification and elimination of the
adverse influence of small geometric model features on the quality of
automatically generated meshes, using local mesh modification operator
s, are addressed. The definition of mesh validity with respect to the
geometric model is extended to include multiple mesh entity classifica
tions. Checks based on mesh topology are used to ensure no dimensional
reductions in the locally modified mesh. Example geometric models of
varied complexity containing small geometric features are used to demo
nstrate the ability of presented procedures to improve mesh quality in
terms of aspect ratio and small angle metrics.
