The ease of use is the most amazing feature I found in Vensim. It is easy to learn and it is the best tool to practice system dynamics. It is relatively fast and has various features that cover all we need in system dynamics. The tool also has the easiest way of presenting the results. One can show the results by only clicking on the graph or table and they can be easily exported. The SyntheSim mode, let modelers check how change in one parameter will affect different variables immediately. Even plotting the causal loops in Vensim, makes a model that is very easy to communicate for presentations and posters. Review collected by and hosted on G2.com.

Some limitations like changing the way of optimization and its formula are the only thing I don’t like. This software is not that technical to have different ways of optimization and in very rare cases, one may need to export the data and apply their own method of formulation to it.

Vensim models

Process flow charts, loops and arrows, graphs and results! Review collected by and hosted on G2.com.

Lots of variables to learn prior starting to implent it! Review collected by and hosted on G2.com.

At first glance,it appears to be a very simple program. Some functions are very intuitive. The outputs it gives are very helpful for simulations. Review collected by and hosted on G2.com.

I very much dislike the graphics of the program. It looks like microsoft paint. Additionally, when trying to do more advanced things or get the program to do what you want, its a huge pain. Error messages are unhelpful in fixing the algorithms. Review collected by and hosted on G2.com.

Flexibility to draw. It also has a feature of simulating two systems altogether and compare the results. Very apt for System analysis and actor mapping. Review collected by and hosted on G2.com.

It is sometimes tricky to delete the arrows that can be made user-friendly. Review collected by and hosted on G2.com.

The stock and flow diagram is easy to create and understand. I learnt it without much help and just using online resources. Review collected by and hosted on G2.com.

Zoom in and zoom out feature of the model decreases the quality of the screenshots Review collected by and hosted on G2.com.

It is really beneficial in development of model equations Review collected by and hosted on G2.com.

It could use more colours to make it appealing. Review collected by and hosted on G2.com.
