查询词典 substitution method

Because the coupling condition of NNGFM arises from the net current continuity imposed at the volume element interfaces, the relatively complex conversion formulation for partial current continuity condition of NGFM is unnecessary when applying G. E. T., and computation time is saved. The coefficient matrix of the coupled equations is tridiagonal, so it can be solved by forward elimination and backward substitution method.
