Claytex sponsor and present at the virtual American Modelica Conference 2020.
The Modelica Conference, organised by the Modelica Association, is the main event for users, library developers, tool vendors and researchers to share their knowledge and learn about the latest scientific and industrial progress related to Modelica and to the Functional Mockup Interface (FMI). The program will cover modeling of complex physical and cyber-physical systems, as well as tools, for a wide range of research and industrial applications. All contributions are peer-reviewed and selected by the Program Committee.
Scope of 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 companion Modelica Standard Library has been utilized in demanding industrial applications, including full vehicle dynamics, power systems, robotics, hardware-in-the-loop simulations and embedded control systems.
The Functional Mockup Interface (FMI) is a freely available 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 utilize Modelica models in non-Modelica environments.

Dymola and Simulink in Co-Simulation: A Vehicle Electronic Stability Control case study
Vehicle development processes have evolved in line with the evolution of vehicles themselves. As vehicles have become ever more complex, integrating electro-mechanical systems into the driving experience, Original Equipment Manufacturers (OEMs) by necessity have had to review and update development processes. Coupled with a desire to eliminate waste for efficiency reasons, OEMs have been driven to use simulation as a core element during development, where the modern vehicle is a classical multi-domain simulation problem. This presentation is a case study, using the Modelica VeSyMA – Suspensions library as a basis for full vehicle control systems development within Simulink, where the user wishes to take advantage of the individual benefits of Dymola and Simulink.
A VeSyMA – Suspensions library slalom test configured for interfacing an external controller
Deploying models as FMUs using the FMI standard interface is a common solution to this; co-simulation enables models to be simulation environment agnostic. Whilst a robust answer to the question of how to deploy models across different simulation tools, it does present a new skill and another variable for users to understand. This case study offers insight with regards the effect of utilizing FMU deployment in such a multi-domain vehicle simulation task.
In order to understand the effects of deploying VeSyMA based vehicle experiments outside Dymola, an Electronic Stability Control (ESC) experiment is presented, benchmarked across both simulation platforms with and without control software in both Dymola and Simulink. An off the shelf vehicle slalom experiment is taken from the VeSyMA – Suspensions library and with minimal pre-processing, exported and deployed as an FMU within Simulink. A control model built in Simulink to the same specification as the one found within the VeSyMA – Suspensions library and is used to demonstrate the validity of the vehicle experiment model exported from Dymola when deployed in Simulink, with and without control algorithm presence. Commentary is given as to the effect of FMU deployment on CPU time and results.
