eFMI® Tutorial on air

[BÜRGER Christoff]

Dear eFMI Community,

The recording and slides of the eFMI® Tutorial presented at the 15th International Modelica Conference (9th of October 2023) are now public available on YouTube (videos) and the eFMI website (slides & videos).

Participants feedback

We had about 50 participants from 20 organizations, including (in alphabetic order):

• Airbus
• BDR Thermea
• BMW
• Boeing
• Carrier
• Fraunhofer IWES
• IKERLAN
• Institute of Vehicle Engineering (iVH)
• LG Electronics
• Mercedes-Benz
• MITSUBISHI ELECTRIC
• Vaillant Group

The feedback has been great! Close to all participants managed to follow the hands-on, for which we provided a portable Dymola & CATIA ESP with all required tooling like compilers, libraries etc included. Many of the participants got really excited and contacted me throughout the rest of the conference to discuss feasability of eFMI in their application domain. The only drawback I see, is that I didn't manage to visit anymore conference presentations due to being captured in eFMI discussions.

Content overview and links

The complete tutorial is split into several independent parts:

• Part 1: eFMI® motivation and overview
• Part 2: Running use-case introduction
• Part 3: Hands on demonstration in Dymola and CATIA ESP
• Part 4: Live demonstration in TargetLink
• Part 5: Short presentation of further tooling

The tutorial covers the current state-of-the-art of available eFMI tooling, including a high-level introduction to the eFMI Standard (Part 1), and a hands-on experience of eFMI technology for selected Modelica example models (Parts 2 & 3). It shows how to configure a tooling workflow from acausal physics models in Modelica down to embedded target code (Parts 3 & 4) and investigates the generated eFMUs and their various intermediate model representations. The focus is on the non-functional quality criteria satisfied by the generated solutions, like traceability within eFMUs, MISRA C:2012 conformance of generated production code and other code quality criteria like static memory allocation and error handling.

Relevance for eFMI

The tutorial provides excellent marketing material to motivate and demonstrate our eFMI ecosystem – in particular the available commercial tooling – and get interested customers started with what we have; emphasis on interested, meaning the target audience has some rough idea/motivation why eFMI might be useful for their domain (for example from the eFMI website) and is now willing to take the next step to invest a bit more time for a hands-on how to get started.

I personally consider the tutorial as one corner stone of our get-started-with eFMI documentation and promotional material; I consider it a living document and I like to keep the material updated.

To that end, I need Your help: It would be very kind if you can find the time to check the material and provide feedback on what we need to improve! Your feedback is very welcome!

Best Regards,

Christoff Bürger
