A typical approach for the development of multi-domain systems often carries the risk of high non-conformance costs and time-consuming re-engineering due to the lack of interoperability between different domains. In its research project "Mechatronic Design", the Siemens AG develops an integrated, model-based and simulation-focused process to perform a frontloading engineering approach for multi-domain systems. The paper presents two use cases from this project as two implementation approaches to system modeling and simulation being synchronized at early design phases. Both use cases utilize the standardized system modeling language SysML and the multi-domain simulation language Modelica. One use case evaluates the standardized OMG SysML4Modelica profile for transformation between SysML and Modelica. The other use case uses a Modelica independent and proprietary profile aiming at more flexible usage. For both approaches, advantages and disadvantages are identified and compared. Depending on the project objectives, the general suitability of the approaches is also judged.
