Geometry-based Adaptive Mesh Generation for Domains with Interior Constraints

摘要

Previous geometry-based adaptive methods usually only consider the geometrical boundaries of manifolds, rarely discuss the models with interior constraints, especially the cases with self-intersecting boundary constraints. This paper extends the existing geometry-based adaptive methods, presents a sizing-field correcting algorithm and a new boundary recovering algorithm to deal with the boundary constraints, including the boundary constraints with self-intersection. Experimental results show that the algorithms can help to generate high-quality mesh with rational transition for the complex models in the practical applications.
