European Automotive Simulation Workshop 2015











About 20 years ago, when crash simulation was already state-of-the-art in the automotive industry, there was the vision to apply a similar simulation strategy to electrical and electronic systems: virtual engineering and testing by means of EM simulation tools at the earliest possible state of development.

Powered by the success of numerical methods when applied to antenna systems, the engineers were excited and keen to also run EM simulations in the area of electromagnetic compatibility (EMC). The idea at that time was to implement simulation strategies for the entire vehicle in order to analyze emission and susceptibility effects including the automotive cable harness, control modules (PCBs), actuators, sensors, antennas, the battery and so forth – all in one go. Unfortunately, simulation methods, software engineering, and hardware capabilities in those days were still behind the requirements for a smooth virtual prototyping and simulation workflow, and so the first enthusiasm passed quite quickly.

Looking back from today’s perspective, it is clear what the problem was: EM software vendors were still relying on single numerical methods like MoM, MLFMM, FIT, BEM, TLM, PEEC, FEM, or others and either running simulations in time domain or in frequency domain.  Only a few visionaries understood then that there isn’t just the one and perfect numerical method for all applications and that real life simulations actually demand hybrid methods which are optimized with respect to minimum wavelength, mechanical structure, aspect ratio, band width, resonant behavior and so on. As an example: onboard electronics pose unique challenges for electromagnetic simulation, due to the difference in scales between different components because in a typical sensing or communication system, the individual traces on a high-speed PCB can be measured in micrometers, the antennas are on the order of millimeters or centimeters, while the chassis that the whole system is mounted on is several meters long.

To help engineers to simulate these components together, CST included the most popular numerical methods in one single Graphical User Interface (GUI) and therefore greatly simplified the EM simulation workflow. Later on, CST developed the System Assembly and Modeling (SAM) framework, which builds on the advantages of Complete Technology by automating the process of simulating complex systems of components. Because of these achievements, electromagnetic simulation finally became a vital part of the automotive design process.
As vehicle electronics get more complex and development cycles tighter, simulation is crucial both for developing new components such as automotive radar, inter-vehicle communication systems and on-board computers, and for increasing the efficiency of tasks that were traditionally done by experimentation, such as electromagnetic compatibility (EMC) and electromagnetic interference (EMI) analysis, antenna placement and cable harness layout.
There are four main application areas in automotive industry where EM simulation tools are employed:

  •          Microwave & RF (antenna design, antenna placement, RADAR components, …)
  •         EDA – Electronics (chip-package-PCB co-design, connectors, cables, …)
  •          Low Frequency (sensors, actuators, bus bars, motors, …)
  •          EMC & EMI (emission, susceptibility, antenna-cable coupling, measurement devices, …)


Due to the close linking and interaction of electronic devices there is a need for interdisciplinary knowledge exchange both on hardware and simulation side. There have been quite a large number of automotive conferences and exhibitions in the past, however most of them were mainly concentrated on hardware and manufacturing business with relatively small attention on simulation matters.
The CST European Automotive Simulation Workshop is a tribute to the immense success of EM simulation. It offers an excellent opportunity to meet engineers and scientists from industry, research and universities on automotive applications.
We are thrilled that we have three keynote speeches from BMW AG, Continental AG, and Robert Bosch GmbH and fifteen talks from research and industry in all four application areas. In addition, CST will present both current technology and the newest developments in EM simulation, together with application examples relevant to the field.
The workshop will take place at an outstanding location with striking architecture and inspiring environment: The BMW Welt Event Forum. BMW Welt is a multi-functional customer experience and exhibition facility of the BMW AG, located in Munich, Germany. In direct proximity to the BMW Headquarters and the Olympiapark, it is designed to present the current products of BMW and be a distribution center for BMW cars. It is just the right place to offer an event forum and conference center for the European Automotive Simulation Workshop.
There will be two plenary sessions and three parallel sessions during the workshop, an early-morning welcome reception, coffee breaks in the morning and the afternoon, and a “gemütlich” lunch break served by Käfer Catering that gives you enough time for networking and communication.

Be part of it and explore what’s coming next in automotive EM simulation. We look forward to seeing you there.

This workshop will take place on 23 November, 2015 in Munich, Germany. Register now to join us.
