An online SMS community meeting with a 90-minute duration. SMS Community meeting #71 – April 2025

Agenda

• Welcome & Introductions - Frank Popielas, Co-Chair SMSWG
• Update of SMSWG activities - Peter Coleman, Chair SMSWG
• Main Presentation -"Update of Modelica Association Standards"- Hubertus Tummescheit, Model Based Innovation LLC, and Modelica Association Board

The Modelica Association develops a set of coherent and related standards for systems simulation. Originally released in 2010, the FMI (Functional Mockup-Interface Standard) continues to evolve, with adoption still increasing, despite over 220 tools already supporting it. The SSP (System Structure and Parameterization) standard is a standardized data format for simulateable systems and describes hierarchical system components and connectivity for FMI- and Modelica based components.In this talk, we will present three related topics:

1. Update and scope of the FMI 3.0 standard, released in 2023
2. The SSP 2.0 standard, released in Q4 2024
3. The concept of Layered Standards, with examples from the FMI and SSP standards

Layered standards allow us to build bridges between e.g. domain specific standards and the industry-agnostic Modelica standards in a way that keeps the base standards simple, and hooks into the parent standard in a pun intended, standardized way.

We’ll conclude the presentation with a Q&A.

• Next meetings: Update for 2025
• Open Discussion
  
  

Speaker

Hubertus Tummescheit is the President and Chief Engineer of Model Based Innovation LLC., and a co- founder of Modelon. Model Based Innovation LLC provides software solutions and expert services to organizations that use model-based simulation tools to design and develop cyber-physical systems.

He has been involved in the Design of the Modelica language from the beginning and is the developer of a number of open source and commercial Modelica Libraries in the energy and HVAC domains. In 2003 he worked as a research scientist at United Technologies Research Center and returned to Sweden in 2004 to start Modelon AB, the first company fully dedicated to tools and services based on Modelica and FMI. Dr. Tummescheit is also a member of the board of the Modelica Association, and of the FMI steering committee. He is active in the future development of both standards.

Dr. Tummescheit has served as the CEO of Modelon AB from 2004 to 2012 and moved to Hartford, Connecticut in 2013 to establish Modelon as a leading force of innovation in system simulation in the United States of America. Since 2024 he leads an independent consultancy organization that is dedicated to help customers implement the digital thread for model based product development and digital twins for product operations.
