ASCEND is a free, open source, mathematical modelling system developed at Carnegie Mellon University since the late 1980s [Piela, McKelvey and Westerberg, 'An introduction to ASCEND: its language and interactive environment', http://dx.doi.org/10.1109/HICSS.1992.183516] . Its main uses have been in the field of chemical process modelling although its capabilities are general. It includes nonlinear algebraic solvers, differential/algebraic equation solvers, nonlinear optimisation and modelling of multi-region 'conditional models'. Its matrix operations are supported by an efficient sparse matrix solver called "mtx".
