Vertex-Ball Spring Smoothing: An efficient method for unstructured dynamic hybrid meshes

Unstructured Remeshing Using an Efficient Smoothing Scheme

Abstract. In this paper, a method for adapting existing 2D and 3D unstructured meshes to modified domain boundaries is presented. The method simultaneously employs mesh smoothing, moving and untangling. It should be considered as an alternative to mesh regeneration often used in either optimization or unsteady flow computations with moving boundaries. With respect to the widely used Laplacian s...

Force-Directed Methods for Smoothing Unstructured Triangular and Tetrahedral Meshes

Parallel dynamic graph-partitioning for unstructured meshes

A parallel method for the dynamic partitioning of unstructured meshes is described. The method introduces a new iterative optimisation technique known as relative gain optimisation which both balances the workload and attempts to minimise the interprocessor communications overhead. Experiments on a series of adaptively refined meshes indicate that the algorithm provides partitions of an equival...

Multislope MUSCL method for general unstructured meshes

The multislope concept has been recently introduced in the literature to deal with MUSCL reconstructions on triangular and tetrahedral unstructured meshes in the finite volume cell-centered context. Dedicated scalar slopes are used to compute the interpolations on each face of a given element, in opposition to the monoslope methods in which a unique limited gradient is used. The multislope appr...

An Efficient Mesh Simplification Method with Feature Detection for Unstructured Meshes and Web Graphics

This paper presents an efficient method of mesh simplification for geometric 3D models. The transmission of 3D models on the Internet is an important task. The data size of a 3D model is usually large to enable more detail to be represented. Hence, it is necessary to represent the 3D model while keeping the data size small and preserving its features, even if the meshes that constitute the mode...
