The two week long System Modeling Study Group (5) uses the Wolfram System Modeler: An Introduction course as part of the day lectures. The Wolfram System Modeler is a separate application and is based on the open source Modelica language. In the study group, we simulated chemical reactions, thermal conductivity of walls, the electro-mechanics of a joystick, a DC motor, and a heater, for example. The System Modeler uses the Functional Mock-up Interface (FMI) and can interface with more that 150 tools. We installed StandardFirmata into an Arduino to demonstrate a control applications with System Modeler.
My efforts to improve my Wolfram Language skills continues with the Wolfram U daily study group on the the Wolfram Language Programming Fundamentals. This Study group ran four days a week in May 2020 and required passing four quizzes. Again, thanks to Wolfram for running the program.
