Well, Nastran is an industry-leading, linear and nonlinear
finite element analysis solver.
Therefore it would be nice if system matrices generated by
NASTRAN  could be imported by SciPy.
There are other finite-element packages, e.g. PERMAS 
which supports the output of system matrices in a
user-friendly way :-)
You can use
K = coo_matrix((vals,(rows,cols)))
Abaqus 6.7 supports the output of system matrices, too.
I am not familiar with Ansys  but I think there exists
a way to export system matrices as well.
