Waves by Finite Element Analysis

This book, which is a sequel to "Fields of Physics by FEA, An Introduction", illustrates

electrodynamics and wave mechanics by FEA, exploiting the convenient features of

FlexPDE.  In order to profit from this approach to the understanding of fields you should

type the problem descriptors yourself, run them, modify them, and consider how the results

compare and connect to theory. The files included are a selection of examples from the book,

which you can run directly and even modify by trying different values in the DEFINITIONS

section. Those examples will provide the flavor of the book. You can also solve problems

of your own, but the number of nodes will be restricted.
