Watertight Anisotropic Surface Meshing Using Quadrilateral Patches
This paper presents a simple technique for generating anisotropic surface triangulations using a generic unstructured quadrilateral decomposition of CAD entities that map to a logical rectangle. Watertightness and geometric quality measures are maintained and are consistent with those obtained using CAPRI’s default tessellation algorithm. Output surface triangulations using the new method meet user specified criteria for chord-height, neighbor triangle dihedral angle, and maximum triangle side length. This discrete representation has hooks back to the owning geometry and therefore can be used in conjunction with these entities to allow for easy enhancement or modification of the tessellation suitable for grid generation or other downstream applications.
