Foil 19 Traditional Iterative Methods as Special Cases of Artificial Time Diffusion Formalism

From CPS615 Module on Iterative PDE Solvers CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
Different Choices of c1, c2, "k" give
Either Jacobi Iterative Method
  • This is "k" = k
    • c1 = 1
    • c2 = 0
or Gauss Seidel
  • This is gotten with a particular choice of "k" as sometimes k and sometimes k+1
    • c1 = 1
    • c2 = 0
Over relaxation
  • Choose suitable c2 as nonzero value
