German automotive industry heavily relies on HLRS simulation expertise

22 Jun 2011 Hamburg - Uwe Woessner from the High Performance Computing Center in Stuttgart (HLRS) was the second speaker in the "State of the Art in Visualization" session. He shared his enthusiasm for automotive industry visualization and virtual prototyping with the audience and explained how you can build up a virtual test drive from hybrid prototypes. It is hard and serious business indeed but also a hell of a lot of fun.

HLRS is one of three supercomputing centres in Germany. The centre is installing new Cray for simulation. HLRS is known for its industrial collaborations with Porsche, Daimler, Kaercher, Bertrandt, and many other well-known German companies, Uwe Woessner introduced.

The product development process in automotive development consists in three phases: planning, developing and going into production. In all these phases, simulation is used.

The building blocks of a simulation workspace are the virtual reality (VR) user interface, the tools including visualization and simulation, and the workspace providing virtual reality, augmented reality, and a desktop. Hybrid prototypes are a mixture of physical and virtual objects. The COllaborative VIsualization and Simulation Environment (COVISE) consists of modules that you can combine.

Opencover is the COvise Virtual Environment Renderer. It is a flexible plug-in system with support for projection based VR and augmented reality. The VR User Interface is important for the user to work intuitively. The API resembles that of QT or AWT.

The Tablet-PC User Interface provides easy input for text and numbers, guarantees precise interaction and is independent of frame rate. There is also the development of optimized complex GUIs which are scalable from smartboards.

Uwe Woessner explained the simulation analysis, starting from the process integration. The steps are geometry generation with room for geometry modification; mesh generation with possibility for mesh refinement; domain composition with a number of domains and algorithms; simulation; post-processing; and visualization.

Simulation coupling exists for different codes including StarCD, CFX, etc. The physical prototypes are being integrated into the process. Uwe Woessner showed examples of the deep tracing of a cup and of computational electrodynamics.

He also showed the interactive simulation in architecture at the Technical University in Vienna for the Masterplan Seestadt Aspern: the building of a new citypart. The air conditioning of the racks in the HLRS server room is also being simulated.

Parallel post-processing is getting mor popular because the data-sets are getting larger and larger.

Therefore, parallel visualization is needed, next to parallel rendering and remote rendering using VR on the

desktop.

GP-GPU post-processing is also on the rise. It is an extension of parallel processing using a visualization cluster with multiple nodes, multiple CPUs per node, and highly parallel GPUs for data processing on GPUs.

In the CUDA ISO / Cutting Surface Computation elements are classified and the number of vertices. The process is performed as follows: selecting an exclusive prefix, reducing (scattering), interpolating and generating triangles.

Parallel Surface Extraction is a process that consists in parallelization of iso-/cutting surface extraction for interactive post-processing of unstructured grids.

Interactive texture based flow visualization is executed with line integral convolution. The interactive LIC comparison results in 64 vector field evaluations and 1 vector field evaluation.

Parallel Particle tracing is used for the simulation of erosion in a turbine runner.

For the validation in the automotive industry, a project has been set up called VALIDATE. The validation process is performed with 3 degrees of freedom; 3 linear motors; and a-max 2g. A haptic simulator is being used.

Third party vehicle simulation are performed by means of standard tests, e.g. lane change test; evaluation of driver assistance systems; testing of new HMI concepts; driver reaction in critical situations; and visibility studies, Uwe Woessner concluded.
