HPC-OM
HPC-OpenModelica for Multiscale Simulations of Technical Systems and Applications for the Development of Energy-Efficient Working Machinery (HPC-OM)

The aim of our research project is the application-oriented development of innovative algorithms and an HPC-software for the performance of multiscale machine simulations. The project is part of the OpenModelica program.

The central idea of this project is to use mathematic as well as syntactic context information, taken from sub models, for the development of a total system. This could then be simulated with high parallel efficiency despite its multiscale phenomena.

The challenges the HPC-software is faced with are located in the automatic analysis, the annotation and partitioning of model graphs as well as in the creation of optimized and load balanced HPC-codes. At the same time we are working on high-detail models of subsystems and a robust coupling of HPC and VR-systems. Simulations of construction machines in their employment context are used to test the algorithms, methods, concepts and models, applying high detail models of Bosch-Rexroth-drive train components.

HPC-porting enables us to conduct multi-physical simulations on the level of detail required for the energy optimization within an acceptable time frame. We are further capable of performing real-time for VR-applications. The development of the open-source software OpenModelica guarantees the sustainability of findings through the cooperation of a big research community. The developed technology will be used by the simulation software of Bosch-Rexroth and the ITI GmbH.
