| [[Modelica]]-based modeling and simulation environment. Modelica is an object-oriented, declarative, multi-___domain modeling language for component-oriented modeling of complex systems. Next to the free [https://github.com/modelica-3rdparty/SystemDynamics System Dynamics library], which is exclusively based on modeling signal flows, there is a free [https://github.com/modelica-3rdparty/BusinessSimulation Business Simulation Library (BSL)] dedicated to System Dynamics, which makes use of Modelica's acausal connectors to account for transitions of conserved matter.

| Stochastic and deterministic modelling and simulation based on the System Dynamics approach to [[Continuous simulation|Continuous System Simulation (CSS)]]. Includes tools for optimization/parameter estimation, sensitivity analysis, and statistical analysis and presentation of results from multiple simulations of stochastic models. Based on the [[InsightMaker]] -engine, stock and flow models are constructed in a click-and-draw manner. Mainly intended for education and research where small and medium-sized CSS modelling and simulation is used. Desktop and online versions available.
