MGM is introduced to solve field distributions in 3-D electron optical systems. The difference equation, the discrete form of Laplace's equation, is deduced in 3-D Cartesian coordinates. In view of the smooth effect, MGM combines Gauss-Seidel iteration with a technique known as coarse grid correction. Formulae for restriction and prolongation are deduced and expressed in terms of tensors.

It is shown that in Jameson's algorithm is not an orthogonal stream-lines coordinate system, but a local stream-lines coordinate system instead. Nevetheless, because of the finite-difference discretization in Jameson's scheme is not carried out along the direction of s and n, but along the Cartesian coordinates, the analysis on all terms of the full potential equation in Cartesian coordinates reveals that his scheme does take a back-ward difference along the streamwise exactly at all points in the supersonic flow region.
表明其所采用的坐标系不是真正的正交流线坐标系,而是局部流线坐标系;同时由于Jameson方法并不对s,n进行差分离散,而是在原笛卡尔坐标系下作差分离散,对笛卡尔坐标系下的全位势方程中的各项的分析表明,Jameson方法恰好能做到在超音速点沿真正的流线方向作后差分。
