System Dynamics

François E. Cellier

The System Dynamics library uses Jay Forrester's system dynamics methodology for modeling mass and information flows in continuous-time systems. This methodology has been, and still is, widely used in research within the social and life sciences. The library itself is designed as a low-level graphical library with an interface similar to that of block diagrams. Another feature of the System Dynamics library is that differential equations are hidden from the user by using terms like levels and rates instead of state variables and state derivatives.


  • Hierarchical and large-scale modeling of system dynamics models
  • Modeling of mass and information flows
  • Socio-technical modeling
  • A rich example collection for multiple domains
  • A library design that resembles traditional system dynamics modeling tools
  • Allows the combination of components from the System Dynamics library and components from the Modelica Standard Library
