Foil 13 Comments on Computational Electromagnetics

From CPS615-Linear Programming and Whirlwind Full Matrix Discussion Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 5 Decemr 96. by Geoffrey C. Fox *
Secs 300.9
Read the literature (for example, Computer Physics Communications, Nov. 1991) for choices of and . Clearly one will take as functions for which can be easily calculated.
Comments:
  • With N expansion functions - the computational work is
  • if We have N grid points
    • with best methods, work is
    • with worst methods, work is
  • However, wave equations have "oscillating" solutions. These could be very hard to represent numerically with finite differences and grid points but could be just fine if oscillation embodied as oscillating expansion functions.
