Industrial user presentations require only an abstract and a presentation, and will be reviewed by the conference board. Authors of accepted papers and user presentations will have to submit a signed Copyright License (Word document) or (PDF) to EasyChair.

Preparation of full papers

The template has been updated for the 2021 conference, so do not use older versions of the template. Note that a nearly finished draft paper is the expected minimum for the submission deadline, papers with only an abstract, or only promised results, will be rejected. Please use the LaTeX template for the creation of full papers. There is also a Word template that is based on the LaTeX template. The Word template contains some wording specific to LaTeX packages; when drafting a document in Word, please make the contents look similar to what the LaTeX templates produce. For draft paper submissions, you may also use other templates (but include an extra page at the end stating you will use the correct template for the final submission).

Please make sure that your submission has been created according to the Modelica Formatting Guidelines.

For the final submission, there will also be the possibility to submit Modelica example model files that correspond to your publication. These files will then be attached to your paper in the Modelica Association copy of the proceedings (but not the LiU e-press copy to which the DOI points).

To announce your presentation, we encourage all presenters to post on social media with a nice picture. You may use this template.

Preparation of Industrial User Presentations and corresponding One-Pagers.

There are no specific templates for industrial user presentations itself. The presentations follow the same guidelines as for full papers.

To inform all participants about your presentation, a one page abstract of your presentation shall be included in the program. To enable a uniform look, please follow this example format. The Word or Latex Template files are found in the corresponding repository.

Technical equipment for presentations

Papers must be presented during the conference in person. Papers that are not presented will be retracted. Presentations will probably be 20 minutes long with an additional 5 minutes for questions.

Industrial User Presentations instead of Poster Session

Papers that are not accepted for a full paper presentation may still qualify for an industrial user presentation, it it is industrially relevant content by end-users, but not vendors, if the content is interesting, but not qualifies for a rigorously reviewed paper. We will let authors know of that possibility at the time of the paper acceptance.

Formatting Guidelines

Guidelines for the formatting of Modelica Conference Papers

Please note the maximum acceptable length of full papers is 10 pages. It can be exceptionally extended up to 15 pages upon request to the Program Chair.

The formatting guidelines for the Modelica Conference papers are listed here.

• File format: The final paper should be sent in Adobe PDF. Please embed all fonts in your final paper to avoid problems.

Paper layout should be 2 column. If you use the paper templates without changing margins or paper format, they should be correct.

Detailed formatting instructions are included in the paper templates. The following is just a summary.

• Page numbers and header/footer: Do not use any page numbers, headings, or footer lines, as these will automatically be added when preparing the conference proceedings. However, footers from references in the text (not footer lines) are allowed.
• Typeface: For the main text of your paper, use 10.5 pt Times New Roman, Times Roman type or the nearest equivalent font. Do not use any other fonts in your document except Courier or Courier New for verbatim code. Verbatim code in Courier font in separate paragraphs should be 9pt, whereas verbatim code snippets inserted within ordinary text paragraphs should have 9.5 pt size.
• First page: At the top margin, type the title of your paper (use 17 pt size boldface Times New Roman). Titles should not exceed three lines. Leave a space and type the author’s name, organization and address. The authors name(s) should be in 12pt font, the organization and address lines should be in 10.5 pt font; but email addresses should be in 9.5pt Courier New font.
• Abstract: Following the author’s name and address, type the abstract of your paper. Use 12 pt bold for the heading. Your abstract should be 100 to 150 words and should be an informative, self-explanatory summary of the paper.

• Figures and tables: Figures and tables should be inserted into the the text just after they are mentioned in the text. Include a caption for each figure/table. Number the figures and tables as they appear in the text (Figure 1, Figure 2, etc). Type figure captions below the figure. Type table captions above the table. The proceedings will only be published in electronic form, so you can include color pictures; however, be aware that readers could print them using black&white laser printers, so the diagrams should also look reasonable when printed in grayscale. Use at least 10 or 11 pt font size for text in the figures (e.g. labels or legends), since it may become unreadable if the paper is resized for printing.
• References: At the end of your paper, include a list of references, using Harvard-style (author-date) citations. Make sure that every reference is cited in the text, e.g. as (Pantelides, 1988). For LaTeX, the paper class provides the options to use.
• Length of paper: The minimum requested length for papers is 4 pages. The maximum acceptable length is 10 pages. However, since we no longer provide hard copies of the proceedings, we’ll accept full papers up to 15 pages, if the authors have very good reasons to exceed the 10-page limit.

Keynotes

15 Years Functional Mock-up Interface – a Journey from FMI 1.0 to 3.0 and the Road Ahead

Christian Bertsch, Bosch Research, FMI Project Leader and Modelica Association Board Member

Over the last fifteen years, the Functional Mock-up Interface (FMI) has evolved by addressing real industrial needs for simulation interoperability. What began as a solution mainly for the automotive industry has now firmly established itself as the de-facto industrial standard for tool-independent model exchange and co-simulation across numerous domains. This keynote will trace the journey of FMI from its initial concepts in version 1.0 to the powerful ecosystem of today. The release of FMI 3.0 marks a pivotal milestone in this journey, enabling major improvements that redefine the boundaries of system simulation. This new version introduces advanced co-simulation capabilities, facilitates the development and deployment of virtual ECUs, and seamlessly integrates FMI models into complex optimization and machine learning workflows. These enhancements empower engineers to tackle new challenges in digitalization and automation with greater efficiency and fidelity. Looking to the road ahead, the FMI standard continues to expand through the development of Layered Standards. These domain-specific extensions, built on top of the core FMI framework, enable further improvements and unlock entirely new use cases for virtual engineering. This talk will provide a comprehensive look at FMI’s past, present, and future, celebrating its role as a cornerstone of modern model-based development.

Model-based Digital Engineering Practice for Automobiles

Zhong Yilin, Vice President of BYD Automotive Engineering Research Institute

Leveraging its full-industry-chain advantages, vertical integration, and massive proprietary R&D, BYD has achieved global leadership in new energy vehicle sales. To address the growing complexity of vehicle systems while sustaining this leadership, systematic application of systems engineering methods has become essential across the product lifecycle. This keynote focuses on digital engineering practices with Modelica, exploring three interrelated areas: 1) co-simulation design and validation methodologies for highly integrated vehicle systems; 2) high-fidelity and computationally efficient modeling approaches for diverse R&D scenarios; and 3) engineering implementation of toolchain integration and virtual validation. We are currently advancing Modelica-based digital engineering practices across multiple domains: developing a whole-vehicle digital engineering co-simulation platform that integrates powertrain, thermal management, and chassis control models, realizing seamless cross-system collaborative optimization of power performance, energy efficiency, and handling stability; creating digital models for HVAC thermal management systems that accurately predict cabin thermal load and system power consumption and energy flows, significantly enhancing both energy efficiency and cabin comfort; implementing digital development processes for seat systems that enable early-stage validation of control strategies, vibration-noise characteristics, and comfort attributes through model-driven design and simulation, substantially reducing physical prototype development-cycles; and pioneering AI-Modelica integration that leverages data-driven methods to accelerate model generation, parameter identification, and calibration, substantially improving the intelligence level of complex system modeling. These practices collectively validate Modelica’s critical role in complex multidisciplinary system modeling, offering a new paradigm for enhancing research and development efficiency in intelligent vehicle development.

Xu’s Modeling Method: A Foundation for Hydraulic Digital Twins and Intelligent Components

Xu Yangzeng, Professor, Expert with Special Allowance from the State Council, Editor-in-Chief of “Modern Hydraulic and Pneumatic Handbook”, Consultant of the Expert Committee of China Hydraulic, Pneumatic and Sealing Components Industry Association

The Xu’s Modeling Method, originating from foundational research for the HyPneu software at Oklahoma State University in the 1980s, provides an intuitive framework for hydraulic system modeling. Its core premise is to align the modeling process with engineers’ cognitive paradigms. A key breakthrough was its algorithmic solution to Differential-Algebraic Equation (DAE) problems, validated through the PERSIM software developed under China’s “Seventh Five-Year Plan” national project. The method enables model construction directly from hydraulic schematics by applying Kirchhoff’s law at junctions, reducing all components to two fundamental sub-models: hydraulic resistance (throttle) and hydraulic capacitance (cylinder). This yields an implicit state equation (a DAE). The Xu’s Algorithm solves this via a unified dynamic-static simulation approach, using the Newton-Raphson method iteratively to compute static states and dynamic derivatives over time steps. In the Digital Twin era, the method finds new relevance. Its implicit state equation serves as a potential mechanism model for digital twins, contingent on solving the inverse problem—a current research focus that may incorporate Artificial Intelligence. Additionally, the method offers a theoretical basis for creating “Hydraulic Intelligent Components,” guiding the design of simpler, more efficient constructions from first principles. This positions it as an advancement over the classic Hydraulic Resistance Systematic Theory. Practically, the method is being applied to develop dedicated simulation and digital twin software for a hydraulic robot system manufactured in Shenzhen, demonstrating its ongoing industrial applicability.

The Rise of Computer Intelligence and what it means for System Simulation

Dr Dirk Zimmer DLR, Institute of Robotics and Mechatronics, Oberpfaffenhofen, Germany

We are undergoing a transition period where computer intelligence is rising to dominance. It will become widely available to everyone at an unprecedented level of intelligence and also at low cost. Such transition periods are often highly chaotic and short-term predictions may hence be rather inaccurate. Based on first principles, however, we can predict what ultimately will prevail after the transition has taken place. This keynote shall provide such an analysis to answer the most relevant questions from the perspective of system simulation: Will the use of simulation rise or fall? Will there be a need for system simulation? What will be the use of Modelica in the future? Will mathematical modeling still be a thing for humans and for computers? The keynote will also explain why it uses the term computer intelligence rather than artificial intelligence.

Reflections on AI Safety and R&D Tools for Intelligent Vehicles

Prof. Shichun Yang Professor and Secretary of the Party Committee of the School of Transportation Science and Engineering, Beihang University, China

The report focuses on AI safety and R&D toolchains for intelligent vehicles. Drawing on the team’s extensive research in the system safety of connected and autonomous vehicles (CAVs) and autonomous driving control, it analyzes failure risks in AI perception and decision-making algorithms, as well as functional safety and data security challenges. It further elaborates on a comprehensive safety protection framework tailored for full-scenario autonomous driving. Addressing key industry pain points, the report introduces an end-to-end R&D toolchain for intelligent driving, covering simulation testing and electronic control development platforms, while demonstrating their practical applications in algorithm verification and safety assessment. Finally, by integrating theoretical insights with engineering practice, it explores iterative pathways for advancing AI safety technologies and outlines future directions for domestically developed tools, offering actionable strategies to drive technological upgrades and real-world deployment across the industry.
