提出了一种新的网格生成技术,使插值和离散误差及其梯度最小化。该方法的关键要素是从基于边缘的误差估计构建空间度量。对于N h三角形网格,误差与\(N h^{-1}\)成正比,误差梯度与\(N h^{-1/2}\)成正比,这是最优渐近。数值实验验证了该方法的有效性。
We present a new technology for generating meshes minimizing the interpolation and discretization errors or their gradients. The key element of this methodology is construction of a space metric from edge-based error estimates. For a mesh with N h triangles, the error is proportional to \(N_h^{-1}\) and the gradient of error is proportional to \(N_h^{-1/2}\) which are the optimal asymptotics. The methodology is verified with numerical experiments.
