I took a similar approach in working through a simple 1D problem and applying FEA to it. But it was fairly straight forward to implement mine in SfePy. I don't know what to say about yours, but once you get it figured out, I think it would make an excellent tutorial as well.

Here's yet another plea for help on a "first problem".

I've been trying to learn FEM a little more thoroughly. Being a quantum chemist, I started thinking about looking at idealized 1d eigenproblems using FEA. I worked out some of the integrals, and the result is in the paper that I've added to the group space here:

http://groups.google.com/group/sfepy-devel/web/fem-1d-eigen.pdf

My quantum chemistry background shows through here, as I'm just using the finite elements like a normal basis set, a "pointy" Gaussian, if you will, and computing matrix elements. This isn't the way that real FEA people solve problems, and I'm trying to understand what that entails. I know it's something like:

- create a mesh
- work out a bunch of integrals over the mesh elements
- then a miracle occurs
- write down your final solution
Being a python person as well, I have high hopes that sfepy can help me understand how real FEA solutions work. But I'm still being a little bone-headed, and I don't understand the example files very well.

My hope is that the simple 1d problems that I've provided are simple enough that it wouldn't be too much work for someone (Ondrej?) to show me how to implement them in sfepy. Thanks in advance for any help anyone can offer.
