12th International Modelica Conference – 15-17 May 2017 – Prague, Czech Republic

April 3rd, 2017 by Mahdieh Mehrabi

Claytex exhibit and present at the 12th International Modelica Conference taking place in Prague, Czech Republic.

This year’s conference is organised by the Czech Society for Cybernetics and Informatics (CSKI) and the Modelica Association.

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 and to the Functional Mockup Interface.

The program will cover modelling of complex physical and cyber-physical systems, as well as tools, for a wide range of research and industrial applications. In addition to paper presentations and poster sessions, the conference features several Modelica tutorials for beginners and advanced users, as well as vendor presentations, and an exhibition.


Meet with Claytex

On our stand, we will be showcasing our new range of Modelica Libraries and the FMI Blockset for Simulink and Excel.


1. Investigating the Effect of a Sonic Restrictor in the Intake of an Engine

Abstract – The air induction system is one of the engine subsystems that most influences fuel efficiency and power generation, especially in restricted race engine applications. In this paper, the quasi-1D model of a sonic restrictor is presented, together with its integration in an engine model, in order to investigate the behaviour of the engine power and torque when the choked condition is reached. The study shows how power and torque curves are affected when a sonic restrictor is installed within the intake system and outlines the need of detailed simulations in a restricted engine development process, to avoid steep engine power reductions at high speeds.

2. Model Reduction Techniques Applied to a Physical Vehicle Model for HiL Testing

Abstract – To build a full vehicle model entirely based on physical equations is a challenge (Dempsey M., 2006). To have this model to run fast enough so that it is suitable for Hardwarein-the-Loop testing is even more challenging. The level of detail in the physical representation of the vehicle can always be increased at the cost of simulation time. Even if the performance of the hardware is constantly improving, we still have to compromise. As part of the MORSE (MOdel based Real-time Systems Engineering) project, model reduction techniques are developed and applied to a vehicle model. The results in terms of accuracy and simulation speed are then investigated.

3. Engine Thermal Shock Testing Prediction through Coolant and Lubricant Cycling in Dymola

Abstract – In this work, an acausal multi-domain physical system model is used to study the interaction between an internal combustion engine operation and a range of cooling and lubrication system thermal cycling scenarios. Although the model can be used for modelling a wide range of scenarios, this paper concentrates on the application of engine thermal shock test dynamics prediction through coolant and lubricant cycling. An internal combustion engine is loadcontrolled on a dynamometer. Coolant and lubricant temperature transients are imposed on the engine system. Using freely available and commercial Modelica Libraries within the Dymola environment, the systems integration of the coolant rigs, lubricant rigs and engine is achieved. The rigs and the controllers are validated against test data to create predictive models of such systems for test virtualisation. This allows the user to develop and define control strategies for the tests from desktop, prior to engaging in laboratory tests.
