ASCEND IV is a free, large-scale, equation-based, environment
featuring a strongly-typed, object-oriented model-description
language. ASCEND is designed to reduce the time needed for
creating, debugging, and solving mathematical models by orders of
magnitude in comparison with C++-like and FORTRAN-like languages.
ASCEND includes interactive support tools for modeling, debugging, and solving
systems with tens of thousands of nonlinear algebraic or
differential equations. Including:
