A surface mesh smoothing and untangling method independent of the CAD parameterization [PDF]
Computational Mechanics, 2014 A method to optimize triangular and quadrilateral meshes on parameterized surfaces is proposed. The optimization procedure relocates the nodes on the surface to improve the quality (smooth) and ensures that the elements are not inverted (untangle).

A Derivative-Free Mesh Optimization Algorithm for Mesh Quality Improvement and Untangling [PDF]
Mathematical Problems in Engineering, 2015 We propose a derivative-free mesh optimization algorithm, which focuses on improving the worst element quality on the mesh. The mesh optimization problem is formulated as a min-max problem and solved by using a downhill simplex (amoeba) method, which computes only a function value without needing a derivative of Hessian of the objective function ...

Untangling and Smoothing of Quadrilateral and Hexahedral Meshes [PDF]
Civil-Comp Proceedings, 2012 In this paper, we extend a simultaneous untangling and smoothing technique previously developed for triangular and tetrahedral meshes to quadrilateral and hexahedral ones. Specifically, we present a technique that iteratively untangles and smooths a given quadrilateral or hexahedral mesh by minimizing an objective function defined in terms of a ...

A multiobjective mesh optimization framework for mesh quality improvement and mesh untangling [PDF]
International Journal for Numerical Methods in Engineering, 2013 SUMMARYWe propose a multiobjective mesh optimization framework for mesh quality improvement and mesh untangling. Our framework combines two or more competing objective functions into a single objective function to be solved using one of various multiobjective optimization methods. Methods within our framework are able to optimize various aspects of the

Generation of curved high-order meshes with optimal quality and geometric accuracy [PDF]
, 2016 We present a novel methodology to generate curved high-order meshes featuring optimal mesh quality and geometric accuracy. The proposed technique combines a distortion measure and a geometric L2-disparity measure into a single objective function.
