Hi Kent (and sympy list), So it seems that several people at the same time feel that sympy would be good for generating FE bases at least, in terms of either tabulated data in common sets of quadrature points, or a generated C(++) code, to be re-used later. Thanks for sending your code. I think we could start a new project (at googlecode?) using your code as a good start. Are you ok with a BSD license?
