In this paper a Modelica library for interactive simulation and advanced visualization called ExternalDevices is introduced and presented. Providing support for standard input devices like keyboard and joystick as well as for communication via UDP and shared memory; this library allows the user to interact with a running simulation and process the output data of the simulation in other processes capable of UDP connections. An advanced visualization system replaces the standard Dymola visualization and offers additional features like full-screen viewing; transparency and support for flexible bodies.
