FEA Programming
FEA Programming
(OP)
I am looking for any books with a focus or chapters on FEA programming (or any reference). That is, any with examples or methods shown in theory and code. I am writing a simple program to solve truss models to further my understanding of the methods. Any language is fine, but VB is what I am using.
The basics such as matrix methods and solving F=kD aren’t necessary, I have these covered. But I would like to see how banded solutions are used and other issues that aren’t readily apparent.

Thanks for your help. I actually saw your suggestion for Numerical Recipes in another post. This is a very helpful reference and contains lots of theory and practical methods for coding your own program.
I agree that there is no single algorithm and that copying code is the wrong approach. From what I have learned, it is more difficult to try to "cut-and-paste" code than it is to just write your own. However, it is often helpful to at least get a feel for what various algorithms and codes are used.
For small models, say less than 2,000 elements, do you feel that banded matrix storage is necessary? With current computer speed and memory, it seems like some of the optimiztion methods might not be requried for simplified programs or small models.

You are right, I forgot to mention that book. It has a chapter on basic programing techniques. Also in every chapter it gives coding side by side with theory. You also know how to code nonlinear problem efficiently with this book, since this is basically a nonlinear fem book. Great book. Also you can see Belegundu and Chandrupatla (I may be wrong in spelling), this is a good book for intial programmers, but written in basic.
