- Vensim Causal Loop Diagramming This video shows several ways to build causal loop diagrams in Vensim. We start simple with Vensim PLE, and then illustrate some additional features, like navigation links, that are possible in DSS. The first ten minutes should have you up & running on the basics. https://vimeo.com/179249938
- Collaboration in Ventity This video takes a look at opportunities for team model building in Ventity. Ventity has a modular structure, with each entity and dataset in a separate XML file. That makes it practical to use source control systems (like subversion or git) or sync software (like Dropbox or OneDrive) to manage file sharing and versioning. Once ...
- Model Analysis – World Dynamics This video walks through a critique of the World model that kicked off the Limits to Growth debate, starting with Forrester’s World Dynamics, followed by World3 and the Limits to Growth and many subsequent works. The purpose of this video is not to discuss the mapping of the world models to the real world, though that ...
- Ventity Introduction with Infection Models We were very pleased with our Ventity workshop at the SD conference in Delft. We had a good crowd, with interesting questions and lots of potential applications that will benefit from our new approach. This series of videos walks you through most of the workshop content. The workshop models are in InfectionSeries.zip, and you can get ...

- Vensim’s new partner – Ventity At the System Dynamics Conference in Delft, we showed a complementary new product – Ventity – that solves some problems that can be intractable in most simulation languages. Here’s a quick preview: http://vimeo.com/vensim/ventitypreview There’s a Ventity poster and more detailed white paper in the conference proceedings: Ventity Poster ISDC 2014 Entity-Based System Dynamics White Paper
