Title: Towards a Standard-Conform, Platform-Generic and Feature-Rich Modelica Device Drivers Library
Authors: Bernhard Thiele, Thomas Beutlich, Volker Waurich, Martin Sjölund and Tobias Bellmann
Abstract:There are many cases where simulation applications need to interact with their environment. Typical examples are Human-in-the-Loop (HITL) simulators (including flight, driving, and marine training simulators), Hardware-in-the-Loop (HIL) simulators, but also offline process simulators which cannot operate in a completely self-contained manner and therefore need to be coupled to external applications. Embedded control applications are another related area which requires that applications interact with their environment. The Modelica_DeviceDrivers library, which had its first release as open-source library in 2012, tries to cater for such use cases. This paper describes the library for the first time and reports about the numerous challenges that the project experienced to meet its goal of supporting several platforms and tools within a standard-conform, platform-generic, feature-rich, and easy-to-use Modelica library.

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.
