In product development process of dynamic systems more than one technical field (i.e. mechanical, electrical or combustion technologies) affects the product. It is of particular importance to ensure the functionality of such multi-domain products especially after changing one of the domain-specific sub-process (i.e. CAD-data in mechanical design). This is possible by simulating the system behaviour of the overall product in a multi-domain system simulation. The consideration of the detailed information of each technical domain in the system simulation is not possible at moment. Therefore the relevant information in each sub-process have to be identified and insert into the system simulation. In this contribution focus is set on mechanical sub-process. An application is developed that identifies all changed information of a product design in the CAD-environment and provides this information to the system simulation. A proof of the functionality of the developed procedure in shown in a use case. The piston of a single-cylinder combustion engine model is changed by the designer. After that the developed application is executed and the changed simulation results are discussed.
