一种自适应四面体网格混合插点细化方法
An adaptive tetrahedral mesh mixed interpolation refinement method
摘要
Abstract
In tetrahedral mesh adaptive refinement,the Delaunay-based circumcenter interpolation method faces challenges in complex geometries because to circumcenters may inherently lie outside the domain,leading to worse mesh quality.This study introduces a novel hybrid insertion strategy to address these limitations.The adaptive strategy effectively mitigates quality degradation in complex geometries.It employs a selection mechanism that chooses between edge-splitting and circumcenter insertion based on Topology-Preserving Quality Optimization Metrics,resolving insertion challenges in narrow regions.A surface-facet preservation algorithm results in collaborative optimization of both surface and volume meshes,enhancing overall quality and ensuring uniform mesh transitions.Numerical experiments demonstrate significant quality improvements for complex models.关键词
