"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 efficiency, if you are not willing to hack the compiler code? Why not push the mathematical envelop and use: Sparse Matrix Techniques ?????????????????????? http://www.cise.ufl.edu/research/sparse/matrices/ http://blogs.mathworks.com/loren/2007/03/01/ creating-sparse-finite-element-matrices-in-matlab/ hth, James
