Three-dimensional unstructured tetrahedral and hexahedral "nite element mesh optimization is studied from a theoretical perspective and by computer experiments to determine what objective functions are most e!ective in attaining valid, high-quality meshes. The approach uses matrices and matrix norms

Structured mesh quality optimization methods are extended to optimization of unstructured triangular, quadrilateral, and mixed ΓΏnite element meshes. New interpretations of well-known nodally based objective functions are made possible using matrices and matrix norms. The matrix perspective also sugg
