Create models that visualize and build understanding of how complex systems work and things change over time. Based on Systems Thinking and the language of stocks and flows, models created with STELLA® Modeler serve as practice fields to simulate “what-if” scenarios and discover the “why” behind outcomes.
Use STELLA Modeler to:
  • Build models that simulate your business or other processes.
  • Communicate the interdependencies of a system.
  • Experiment with different scenarios and view results in a graph.
  • Run STELLA and iThink® models (version 10 or greater) created with the desktop version on your iPad.
  • Share models via email with anyone who has STELLA Modeler, STELLA or iThink desktop software (version 10 or greater).

Visualize how systems work

  • Quickly create Stock and Flow diagrams that provide insight into business processes.
  • Build multi-level, hierarchical model structure using modules.
  • Map out the overall causal relationships of a system.
Population Model

Simulate and explore results
