多网格求解泊松方程，给出并解释了一个如何使用多网格求解的过程-I give a short explanation of how to use multigrid to solve the Poisson equation in cylindrical coordinates for a solid conducting pipe. I also explain how to use a non-uniform grid to optimize the problem.

This is a collection of files for the solution of scalar linear elliptic PDEs with a standard multigrid method.
