SyFi - An Element Matrix Factory, with Emphasis on the Incompressible Navier-Stokes Equations
Kent-Andre Mardal 

SyFi  is an open source C++ library for defining and using advanced
finite elements based on  symbolic representations of polygonal domains, 
degrees of freedom and polynomial spaces. Once the finite elements
and weak forms are defined, they are used to generate efficient C/C++ code.
