Final Report for : Surface Generation and Cartesian Mesh Support NAG 2 - 145 8

This paper presents a simple technique for generating anisotropic surfacetriangulations using unstructured quadrilaterals when the CAD entity canbe mapped to a logical rectangle. Watertightness and geometric qualitymeasures are maintained and are consistent with theCAPRI default tes-sellator. These triangulations can match user specified criteria for chord-height tolerance, neighbor triangle dihedral angle, and maximum triangleside length. This discrete representation has hooks back to the owning ge-ometry and therefore can be used in conjunction with these entitiesto allowfor easy enhancement or modification of the tessellation suitable for gridgeneration or other downstream applications.
