Title: Interactive FMU-Based Visualization for an Early Design Experience
Authors: Volker Waurich and Jürgen Weber
Abstract:User experience is an eminent part of holistic product design. Especially in the field of mobile machinery, the driver’s impression of the machine handling is crucial for successful design. To get an early understanding of the ergonomic aspects of a new concept of operation, interactive simulation can be applied. This paper presents the tools to develop a functional prototype using free software and low-cost hardware. This includes prototyping of control devices, interfaces to the simulation models and a generic visualization using a game engine. In order to speed up the process of functional prototyping, an approach to automatically visualizing FMUs based on a scene description file is presented. The application of interactive simulation was used to support the development of a novel control device for excavators in a student project at TU Dresden.

Title: A New Object-Oriented Approach for Integrating Discrete Element Method into Modelica
Authors: Christian Richter, Jürgen Weber, Florian Ohser and Thomas Beutlich
Abstract:In this paper we present a new library for co-simulation of discrete element method and modelica models. For this a component-based approach is used which allows closed modeling and visualization of discrete element systems in a modelica tool. Translation into a native DEM description language and co-simulation is done by a separate compiler and backend. Usage and functionality are shown in a simple use case of a bucket excavator digging a hole.
