Updating meshes on deforming domains

We propose a mesh quality improvement method that improves the quality of the worst elements.

This usually defines a continuous, multivariable optimization problem for which local extrema are sought.Thus, for example, it can be applied to structured, unstructured, and hybrid meshes; it can be applied to triangle, quadrilateral, polygonal, tetrahedral, hexahedral, and polyhedral meshes.With proper target selection, the paradigm permits mesh optimization on a wide variety of applications, including initial mesh quality improvement (untangling, smoothness, angle, aspect ratio, shape, size, and orientation), CFD boundary layer meshes, mesh quality maintenance on deforming geometric domains (design optimization, metals forging, crash simulations), Arbitrary Lagrangian-Eulerian (ALE) mesh rezoning and remapping, mesh alignment, anisotropic mesh smoothing, and optimization of h-adapted meshes (preservation and improvement of local refinements).We used the deforming mesh metric to prototype geometry and mesh update model for potential use in SLAC National Accelerator Laboratory accelerator design studies.Your internet explorer is in compatibility mode and may not be displaying the website correctly.
