在椭圆网格生成的步骤中, 以代数网格作为输入,
需要对其进行 Jacobi 迭代, 从而满足泊松方程,
改善正交性和光滑性, 消除网格折叠.
应当实现两项功能:

  • 指定步长的单步 Jacobi 迭代步骤;
  • 按指定容差或迭代次数自动停机的 Jacobi 迭代流程;
    • 如果精力足够的话, 应当允许以不同的范数计算容差.

在 dffa0e4 中初步实现了这两个函数；实现尚不完整或有效。

应当考虑借助 IterativeSolvers.jacobi 这个函数来进行实现；还需要考虑调用先用的有限差分包是否会是合理的．

当前的实现 (#26) 看起来已经足够使用需要了；套用 IteratorSolver 将使得代码复杂化，暂时不予考虑．
