Modelica training

Modelica and Functional Mockup interface in Energy Systems Simulation

In collaboration with Innovation Fund Denmark Cool-Data project and IEA Annex 56 IoT for Heat Pumps, BuildSim Nordic offers the opportunity for Ph.D. students, post-docs, and researchers to participate in a 3-day Modelica training course.

The training gives hands-on experience with Modelica Language, a language for modeling of cyber-physical systems, the Functional Mockup Interface (FMI), a free standard to exchange dynamic models, and applications in energy system modeling and co-simulation.

The training follows the BuildSim Nordic conference immediately on the dates Aug 24-26.

The training is free of charge. Lunch and coffee is included.

Sign up for the training by sending an email to (with message topic “Cool-Data workshop”). Note that seats are limited.

Intended audience: mechanical engineering, building services, computer science
