This text teaches finite element methods and basic finite difference methods from a computational point of view. It emphasizes developing flexible computer programs using the numerical library Diffpack, which is detailed for problems including model equations in applied mathematics, heat transfer, elasticity, and viscous fluid flow. This edition offers new applications and projects, and all program examples are available on the Internet.Moreover, the heat source f is realized as a redefined virtual function f. We shall use the Heat 2weld ... For this purpose, it is not necessary to understand the source code; one only needs to run the application with ready-made input files. ... Filtering the resulting simres file format to a format required by a special plotting program is explained in Chapter 3.3. ... This is important for making a smooth movie.
