Update (2025-11-21): eFMI® Tutorial 2025 recordings now public available
The recording and slides of the eFMI® Tutorial presented at the 16th International Modelica & FMI Conference (8th of September 2025) are now public available on YouTube (videos) and the eFMI website (slides & videos).
We had about 15 participants from 13 organizations and the feedback has been great! Close to all participants managed to follow the hands-on, for which we provided a portable Dymola & CATIA Software Production Engineering with all required tooling like compilers, libraries etc included. Many of the participants got really excited and used the unique opportunity provided by the conference to discuss the feasability of eFMI in their application domain.
We like to thank each participant for joining the tutorial and your kind feedback!
The tutorial demonstrates the current state-of-the-art of available eFMI tooling in five individual parts, including an eFMI overview, motivating example, hands-on, advanced examples and industry use-case. The respective YouTube recordings are:
- Part 1: eFMI® motivation and overview
- Part 2: Running use-case introduction
- Part 3: Hands-on in Dymola and Software Production Engineering
- Part 4: Advanced demonstrators
- Part 5 (industry case-study): eFMI based thermal management system (TMS) development for fuel cell electric vehicles (FCEV)
Highlights of the tutorial are Part 4, the advanced examples including the new eFMI.NeuralNetworks Modelica library and the battery management system (BMS) demonstrator presented at the DS booth (BMS technical report), and Part 5, the first application of eFMI in industrial production for the thermal management of the fuel cells of an electric vehicle by iVH (presentation slides). Both parts show the steady progress of eFMI tooling and how we can achieve high-hanging fruits with the tooling we already have right now.

We are happy to announce that there will be an extensive eFMI® tutorial at the upcoming 16th International Modelica & FMI Conference, 8-10th of September 2025, Lucerne, Switzerland.
The tutorial will demonstrate the current state-of-the-art of available eFMI® tooling. Participants will get a very high-level overview of the eFMI® workflow from acausal physics models in Modelica® down to embedded target code and a hands-on experience of it for selected Modelica® examples. The generated eFMUs and their various intermediate model representations are investigated, focusing on the non-functional quality criteria satisfied by the generated solutions, like traceability within eFMUs, MISRA C:2023 compliance of generated production code and other code quality criteria like static memory allocation and error handling.
Compared to the tutorial at the last International Modelica Conference in 2023, we will investigate more advanced examples like hybrid physics and neural network (NN) models where unknown non-linear physics are modeled using NN surrogate models well integrated with known physics (so called physics-enhanced neural ordinary differential equations, PeN-ODEs). Also the latest eFMI® improvements will be presented, like tooling to import eFMI® Production Code in MATLAB®/Simulink®, the new standard library of GALEC built-in functions and others.
Expected experience of participants:
- No previous experience with eFMI®.
- Moderate knowledge of Modelica®.
- Good understanding of physics/equation-based modeling.
- Little/moderate knowledge of the embedded domain and its challenges.
Software requirements:
- Participants have to bring their own computer with Windows 10 or 11, 64-Bit, x86.
- Required software will be provided few days before via download and at the tutorial via USB stick.
- Time limited licenses (Dymola®, Software Production Engineering) valid throughout the conference week are provided.
- To provide the download links, participants have to register for the tutorial. Please write an e-mail to Christoff.Buerger@3ds.com (Modelica Association Project eFMI® project leader) that you like to participate.
