SUMMARY

The Poisson Superfish code primarily employs a finite difference method (FDM) approach to construct the linear equation system, utilizing Gauss-Seidel and Successive Over-Relaxation (SOR) techniques for solving it. The discussion highlights that while the code's core is considered classic, its underlying mesh-building tools exhibit characteristics of FDM rather than finite element method (FEM). The consensus indicates that the implementation is a hybrid, capable of solving the Poisson equation through various valid methodologies.

hello,

I want to know that the poisson superfish code uses finite difrerence method or finite element method?

Hi azart,

I've thought poisson superfish uses a "FDM-like" process to build the linear equation system and from thereon proceeds using Gauss-Seidel & SOR to solve it. Am bit out of my field here (perhaps someone else isn't) but my "FDM-like" stems from the age of the code (isn't the core quite a "classic") so the underlying mesh building tools would resemble FDM rather than FEM (in reality probably in between, can solve the Poisson equation in 'fairly many' valid ways). Perhaps someone who is really familiar with this has a better idea and can correct my ramblings :biggrin: .
