The July/August 2005 issue of Computing in Science & Engineering has an article by Michael Tobis about PyNSol (slides from the talk at http://geosci.uchicago.edu/~tobis/PS0/PS3.html ). It appears to be a code generation tool that takes a few equations specified by the user and translates them to Python code using Numarray. The author says the next choice for PyNSol's code generation target will be Fortran 77 -- I think Fortran 95 would be preferable for readability and conciseness.
