  • Doing Classic SD in Ventity

    Ventity extends the System Dynamics paradigm with a number of features that enable dynamic cohorts, agents, networks and other hybrid simulation features. However, Ventity is pretty great for simple, aggregate dynamic models, too. You don’t need to know about its advanced features to put the entity architecture to good use by automating suites of policy

  • Ventity 4.4 release

    This is a full version 4 release. There are no major new features beyond the many introduced in the v4 beta. The emphasis is on speed and memory improvements in the simulation engine. Diagram tool behavior is a little more Vensim-like, with fewer clicks required to accomplish some tasks, and the toolbar now includes a
