Delaunay-Based Anisotropic Mesh Adaptation

Science and engineering applications often have anisotropic physics and therefore require anisotropic mesh adaptation. In common with previous researchers on this topic, we use metrics to specify the desired mesh. Where previous approaches are typically heuristic and sometimes require expensive optimization steps, our approach is an extension of isotropic Delaunay meshing methods and requires o...

A moving mesh method with variable mesh relaxation time

We propose a moving mesh adaptive approach for solving time-dependent partial differential equations. The motion of spatial grid points is governed by a moving mesh PDE (MMPDE) in which amesh relaxation time τ is employed as a regularization parameter. Previously reported results on MMPDEs have invariably employed a constant value of the parameter τ . We extend this standard approach by incorpo...

A Moving Mesh Numerical Method

We show that the possibly discontinuous solution of a scalar conservation law in one space dimension may be approximated in i-'(R) to within 0(N~2) by a piecewise linear function with O(N) nodes; the nodes are moved according to the method of characteristics. We also show that a previous method of Dafermos, which uses piecewise constant approximations, is accurate to 0(N~l). These numerical met...

5A.4 Efficient Delaunay Mesh Generation from Sampled Scalar Functions

Many modern research areas face the challenge of meshing level sets of sampled scalar functions. While many algorithms focus on ensuring geometric qualities of the output mesh, recent attention has been paid to building topologically accurate Delaunay conforming meshes of any level set from such volumetric data. In this paper, we present an algorithm which constructs a surface mesh homeomorphic...
