Explore the contents of this article with a free Wolfram SystemModeler trial. Our goal with SystemModeler is to provide a state-of-the-art environment for modeling, simulation---and analytics---that leverages the Wolfram technology stack and builds on the Modelica standard for systems description (that we helped to develop). SystemModeler is routinely used by the world's engineering organizations on some of the world's most complex engineering systems—as well as in fields such as life sciences and social science. We've been pursuing the development of what is now SystemModeler for more than 15 years, adding more and more sophistication to the capabilities of the system. And today we're pleased to announce the latest step forward: SystemModeler 5.
