本文提出了一种计算二维常平均曲率曲面的方法。所讨论的方法使用问题的变分方面来实现有效的算法。原则上,它是一种类似流的方法,因为它与面积函数的梯度流相关联,从而提供了可靠的收敛特性。在后台,预条件共轭梯度法起作用,它给出了直接椭圆多重网格法的速度。
This paper presents a method for computing two-dimensional constant mean curvature surfaces. The method in question uses the variational aspect of the problem to implement an efficient algorithm. In principle, it is a flow-like method in that it is linked to the gradient flow for the area functional, which gives reliable convergence properties. In the background, a preconditioned conjugate gradient method works, which gives the speed of a direct elliptic multigrid method.
