The source code for all the examples in the book has recently been made available by Wiley. They total 26 MB and can be downloaded by going to booksupport.wiley.com and searching on author: Finlayson (or, title or ISBN number). These would allow you to work all the examples in the book just by loading the source code into the requisite Excel, Matlab, Aspen, or Comsol. The problems at the end of the chapter you still must do yourself!
When I first wrote the book I thought that it was important for students to start from nothing and learn each program. However, I’ve realized that even if you do that, you learn only the things relevant to that example, and still have to learn some more. Now, by starting with an example, whose solution is in front of you, you can learn that problem faster, and, hopefully, continue that learning process when you tackle new problems.
The book web site, http://www.ChemEComp.com has links to the same file stored by Wiley. It has other downloads, as well, that might be useful. Don’t ignore the material on The Method of Weighted Residuals and Variational Principles, which is there, too. It deals with error bounds, and you may be willing to just accept your answer, but the bounds do give you confirmation and useful insight into the method of solution.
