Towards a 3D conceptual architecture framework, based on multi-physical constraints

System engineering is an approach that allows to manage complex multi-physical constraints occurring in mechatronic systems. During the conceptual design phase, the choice of a concept is critical, as it has to ensure that a corresponding 3D physical architecture fulfills thermal, EMC (ElectroMagnetic Compatibility) and dynamic requirements. This paper first focuses on the state-of-the-art of existing methods and tools regarding concept architecture assessment in a multidisciplinary context. The current disciplinary expert processes and corresponding expectations are presented, based on industrial surveys. Then the specifications of the SAMOS (Spatial Architecture based on Multi-physics and Organization of Systems) MBSE approach extension are detailed. This extension aims at evaluating a 3D concept architecture under multi- physical constraints. Finally, the corresponding multi-physical 3D sketcher framework development roadmap is described.
