ASCEND is an interactive environment for modeling, debugging, and solving large systems of nonlinear algebraic or differential equations. Oriented towards chemical engineering applications, it includes the largest open-source thermodynamic properties
... [More]
database. Its interactive design allows users to inspect and solve very difficult nonlinear systems. It includes plotting abilities and is scriptable. ASCEND's efficient design allows solution speeds of the order of 100,000 non- linear equations per second.
Some other commerical and non-commercial tools with similar functionality to ASCEND include OpenModelica, GAMS, Simulink, SciLab, AMPL, EMSO, EES, TRNSYS, Aspen and Dymola.
The ASCEND development team is currently actively working on a new release. We're building a new GTK GUI as well as reinstating support for various external solver engines and external 'black box' relation blocks.
