Abstract
Increasing resolution in computational simulation is enabling the use of original
CAD design models as the basis of mesh generation. Because of varying resolution
requirements, geometric detail removal is a critical part of this process. Three
classes of geometry details are classified by their removal method: direct detail
removal seeks to remove details directly by compositing them with neighboring
topology; blend removal removes blends by first partitioning blends then compositing
the pieces with neighbors; bridge removal requires more advanced decomposition,
and is not described here. Key capabilities for all these methods include defining
a size measure, and detecting geometric details based on those. Blend detection is
also described. Results are given for automatic detail reduction applied to several
real parts.
