Sorry to keep you waiting.
Here is the much awaited update - http://ankitmahato.blogspot.in/2013/09/python-software-foundation-sfepy-gsoc_12.html

So is it resolved?

If things get too complicated, try some simplifications so that we have some
example(s) within SfePy for the GSoC final phase. I will be able to support you
fully from 11.9.

Ok, keep up the good work, and let us know about progress or problems. Once
that solver works, you will have something to compare a new FEM solution with.
