In this paper an approach for handling collision within the Modelica MultiBody library is presented. Therefore; a short overview about collision consideration for multibody simulation is given. Different methods for calculating the contact reactions are discussed and their potentials for implementation in a free Modelica library are deliberated. Furthermore the implementation of this collision library; using a penalty-based collision approach and the Bullet Physics Library for collision detection is described. The application is demonstrated in examples and limitations are brought up. Although some drawbacks restrict usability; the library can be used to increase the level of detail for multibody simulation models.
