The main objective of the the research area "Work Process - Analysis and Simulation" is the ultimately complete simulation of the thermodynamics of the working process. The concrete implementation includes not only the development and optimization of the tools in the following main research areas, but also the testing and application within the framework of industrial cooperations. In addition to the development of the required simulation models for the most realistic possible prediction of the working process, intensive work is being done on the development of metrological methods for improved analysis.
