Does anyone have any experience working with open source process simulators?
There are some of them mentioned in this article:
http://www.simulatelive.com/product-reviews/simulation/review-of-open-source-process-simulators

Has anyone that has experience in process simulation been using any of those?
I'm not so experienced with process simulation and wonder is this a way to start?

Thanks for any *delete me*
