15th Modelica Conference

Dassault Systèmes was one of the gold sponsors and exhibitors of the 15th International Modelica Conference (https://2023.international.conference.modelica.org/which was held in Aachen, Germany from October 9-11, 2023.

We enjoyed the opportunity to meet with so many customers and peers and discuss about Modelica and DYMOLA.


  • What is the Modelica Conference ?

The Modelica 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, and DCP.

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

This year the Modelica conference counted a total number of 280 participants which shows a great interest for Modelica and open standards such as FMI and SSP.


  • Vendor session and competition analysis


Dymola has been granted a brand new PowerBy feature. This new functionality enables the use of the platform as version management system for models while keeping Dymola as primary library development tool. A Standalone tool but now integrated with the 3DExperience Platform tightening  the links between 2D/3D  or other objects of the platform  and Dymola.

A better support of standards such as FMI 3.0  (Early return, Event mode & Intermediate update, Arrays, Terminals and icons…) as well as the SSP standard has been implemented.


A new library from Dassault Systemes called “Process Modelling & Engineering library” (PME library) has been released. It will be well suited for modelling of process plants enabling dynamic simulation of separation processes with backflow streams, evaporation, condensation and control.


  1. Trends
  • Julia


JuliaHub and Dymola are both software tools used in the field of modeling and simulation, but they have different focuses and characteristics:

  1. JuliaHub is a platform that provides a collaborative and cloud-based environment for data science and scientific computing.
  2. It is centered around the Julia programming language, which is known for its high-performance capabilities, making it suitable for numerical and scientific computing tasks.
  3. JuliaHub offers a range of tools and resources for data scientists and researchers, including Jupyter notebooks, Julia-specific packages, and cloud-based computing resources.
  4. It is well-suited for tasks such as data analysis, machine learning, and scientific research where the Julia language's performance advantages are beneficial.


In summary, JuliaHub is more of a general-purpose platform for data science and scientific computing, while Dymola is a specialized software for modeling and simulating complex physical systems. The choice between the two would depend on the specific needs of the user or organization, with JuliaHub being suitable for scientific and data-related tasks, and Dymola tailored for engineering and system simulation in mechatronics and related fields.


  • Trendy topics


A lot of industry players or academic researchers are showing a significant interest in the modelling and simulation of loads and power consumption of processes  involved in the manufacturing of electronic devices  or even in chemical processes.


The rise of Machine Learning  and Artificial Intelligence starts to be noticeable in the Modelica community. Emerging topics such as generative coding/modelling  seem to be popping up.


One of the new surprising upcoming topics is the modelling for medicine and biology. Some academic researchers start investigating models of human bodies, variable structures (cells etc…).


  • Trends from our customers on Dymola


Cosimulation : easy to use cosimulation platforms and numerical difficulties with cosimulation that might be addressed by FMI 3.0 features such as Early-return modeEvent mode and Intermediate update mode.

A lot of key players of the industry seem to like the idea of sticking to standards. They would like to be able to work in tool-independent way. Therefore, supporting standards such as FMI and SSP and keeping up-to-date brings significant value to a tool such as Dymola.
