Resources for the book The Craft of Finite Difference Computing with Partial Differential Equations by Hans Petter Langtangen and Svein Linge.

This easy-to-read book introduces the basics of solving partial differential equations by finite difference methods. The emphasis is on constructing finite difference schemes, formulating algorithms, implementing algorithms, verifying implementations, analyzing the physical behavior of the numerical solutions, and applying the methods and software to solve problems from physics and biology.
