"Octave" is in portage, as it is a matlab sorta package for
fluids.
google for
Octave : Computational Fluid Dynamics : Finite Element Analysis
for starters.
I understand you are smart, but why push the issues on compiler

Why not push the mathematical envelop and use:
Sparse Matrix Techniques ??????????????????????
