Let me announce SFE-00.35.01, bringing per term integration - now each term can use its own quadrature points. This is a major change at the heart of the code - some parts may not work as all terms were not migrated yet to the new framework. All test examples work, though, as well as acoustic band gaps. See http://ui505p06-mbs.ntc.zcu.cz/sfe . SFE is a finite element analysis software written almost entirely in Python. The code is released under BSD license. best regards, r.
