Hexa/Quad Mesh Quality Study

we present a new quality visual analysis system for 3D hexahedral (hex) and 2D quadrilateral (quad) meshes. Our system allows users to focus their attention on areas with poor quality elements without being distracted by the large elements in the mesh model through an aggregated quality glyph. Our system also explicitly highlights places with overlapping elements that are typically hard to see with existing visualization tools. In addition, we display boundary error information in three different forms to support its detailed inspection, which is often ignored by existing visualization tools. Furthermore, multiple views are provided to support a multi-level analysis of the local mesh configuration at places with low quality elements. To demonstrate the effectiveness of our system, we have applied it to analyze the quality of different mesh models and compare the performance of a couple of mesh generation and mesh optimization algorithms for quadrilateral and hexahedral meshes, respectively.
