American Modelica & FMI Conference 2026

The American Modelica & FMI Conference 2026 will be an in-person conference event. The conference will take place at the Georgia Institute of Technology in the Aerospace Systems Design Laboratory from October 12–14, 2026. It is organized by NAMUG, the North American Modelica Users Group, in cooperation with the Modelica Association. Join us in person in Atlanta!

About the Conference

The Modelica & FMI Conference is the main event for users, library developers, tool vendors and language designers to share their knowledge and learn about the latest scientific and industrial progress related to Modelica, FMI, SSP, eFMI, DCP and methods and tools for equation oriented languages. Please take a look at the Call for Papers if you are interested in submitting.

  1. The program will cover processes and tools for the modeling of complex physical and cyber-physical systems as applied to a wide range of research and industrial applications, and will have a new track in this conference that covers technical contributions from equation-oriented languages other than Modelica.

  2. It is supported by many Modelica and non-Modelica tools and is the key to utilizing Modelica models in non-Modelica environments.

For the 2026 conference we will include a new track on the structure and application of equation-oriented modeling languages other than Modelica into the program, since we see many similarities that will enrich a conversation centered on principles of equation-oriented modeling.
We invite users of these other modeling languages to submit their technical publications to this conference, and hope that the broader scope will benefit the growth of equation-oriented modeling.

In addition to paper presentations, the conference features several Modelica tutorials for beginners and advanced users, as well as user presentations, vendor sessions, and an exhibition.

Workshops and Tutorials will be given on the afternoon of October 12th 2026, the keynotes, paper presentations and other parts of the program will be on October 13th and 14th.

In building on the successes of the previous American Modelica conference, we are also happy to announce a Student Best Paper competition.
Additional details are available in the call for papers.

Sponsorship opportunities

The American Modelica conference will be your opportunity to meet your customers again in a personal setting, at a great location. Please stay tuned for details about our sponsorship opportunities, we will post them here in the near future. Note that all sponsors will have the opportunity to exhibit at the conference, and that we don’t offer a separate way to exhibit at the conference.

The American Modelica Conference 2026 relies heavily on sponsors to maintain the affordability of the ticket prices. If you are interested in sponsoring the conference, please check out the conditions at in our call for sponsors and contact us as soon as possible at modelicaNA2026@groups.liu.se.

Keynotes

Pushing the Limits by Open Standards: Enabling Larger, Faster, and More Credible System Simulations

Oliver Lenord

Oliver Lenord, Research and Development Engineer at Bosch Corporate Research, Project leader of OpenScaling project.

Scalability of virtual engineering has become an increasingly critical demand driven by the innovation pressure towards carbon neutral, energy-efficient and cost-effective solutions. Open standards like Modelica, FMI, eFMI and SSP play a major role in making system simulation accessible to a broad user base, fostering a rich ecosystem of research and technology deOvelopment across academia and industry. The European publicly funded project OpenSCALING (Open Standards for SCALable Virual EngineerING) has further strengthened this ecosystem through standard enhancements and new methods, enabling simulation and credible processes to scale to the next level. This talk will highlight key project achievements in the fields of:

Reference to newly developed methods and standard enhancements are given including array-preserving compilation, pre-compiled components, and improved support of sensitivities in FMI. In addition the newly proposed layered standards ls-sa (for sensitivity analysis) and ls-uq (for uncertainty quantification) are briefly introduced.

Benchmarks and examples will illustrate these advances, demonstrating the ability to:

Finally, an outlook will be given on the future potential of agentic AI for Modelica and the proposed Base Modelica language.

Nuclear System Modeling for Integrated Energy Systems Analyses

Daniel Mark Mikkelson

Dr. Daniel Mikkelson is an integrated energy modeling and simulation engineer at Idaho National Laboratory.

The HYBRID modeling repository has been developed to analyze the control, dispatch, and feedback of integrated energy systems that leverage nuclear power for thermal and electrical applications. As global priorities endorse nuclear energy, enabling rapid, open-source, dynamic evaluation of potential nuclear applications can enable faster development of integrated systems that will improve the utilization of nuclear energy in diverse applications for both brownfield and greenfield integrations. An overview of the nuclear approach to modeling and simulation will present areas where Modelica presents an ideal tool to investigate configuration viability in dynamic deployment scenarios.

Scope of the Conference

Modelica is a freely available, equation-based, object-oriented language for convenient and efficient modeling of complex, multi-domain cyber-physical systems described by ordinary differential, difference and algebraic equations. The Modelica language and the companion Modelica Standard Library have been utilized in a variety of demanding industrial applications, including full vehicle dynamics, power systems, robotics, buildings and district energy systems, hardware-in-the-loop simulations and embedded control systems. The Functional Mock-up Interface (FMI) is an open standard for the tool-independent exchange of models and for co-simulation. It is supported by many Modelica and non-Modelica tools and is the key to utilizing Modelica models in non-Modelica environments.

Development in the Modelica Association is organized in Modelica Association Projects:

These projects collaborate to design and maintain a set of coordinated standards for modeling and simulation of complex physical systems.

The Modelica & FMI Conference will bring together people using Modelica and/or other Modelica Association standards for modeling, simulation, and control applications, such as Modelica language designers, tool vendors and library developers. The Modelica & FMI Conference provides Modelica users with the opportunity to stay informed about the latest language, library, and tool developments, and to get in touch with people working on similar modeling problems. The conference will cover topics such as the following:
