iThink and STELLA: leading the world in advanced, easy-to-use simulation

iThink and STELLA are simulation tools developed by isee systems, based on the proven discipline of system dynamics - and 'systems thinking'.

With highly advanced technical capabilities and functionality, iThink and STELLA are also sufficiently easy to enable beginners to build insightful simulations quickly.

These leading-edge simulation tools have been extensively applied and tested in business, public services and universities across the world for over a quarter of a century - and are progressively enhanced with new technology.

Version 9.1 of iThink and STELLA was released in 2008 and includes major new features, including hierarchical models and web-based simulation. Version 9.1.3 released in June 2009 adds more features and security.

IThink and STELLA have exactly the same simulation functionality - but they are packaged for different interests:
