ELIMINATION OF THE ADVERSE-EFFECTS OF SMALL MODEL FEATURES BY THE LOCAL MODIFICATION OF AUTOMATICALLY GENERATED MESHES

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.
