MULTIZONE QUADRILATERAL MESH GENERATOR FOR HIGH MESH QUALITY AND ISOTROPY

Methods for CAD operations and corresponding systems (2100) and computer-readable mediums (2126) are disclosed herein. A method (2000) includes receiving model data (2002) of a surface (210) of a part (200) to be manufactured. The method includes performing a loop-paving process (2004) for a first portion of the surface (210) to produce a first set of elements (302, 304, 306). The method includes performing a Cartesian meshing process (2010) for a second portion of the surface (210) to produce a second set of elements (704). The method includes performing a subdivision meshing process (2016) for a third portion of the surface (210) to produce a third set of elements (1002). The method includes combining (2020) the first set of elements (302, 304, 306), the second set of elements (704), and the third set of elements (1002) to produce a final mesh (1202) for the surface (210) of the part (200) to be manufactured.
