MBSE and SPDM: Connecting System Definition and Engineering Simulation with SysML v2

With the emergence of SysML v2, new opportunities arise to strengthen the connection between system definition and engineering analysis. Two major advances are particularly significant. First, SysML v2 introduces native concepts to describe analysis-related information, including objectives, evaluation criteria, and input configurations. Second, it provides a standardized API to navigate model repositories and access both system definition elements and analysis specifications in a consistent way. These capabilities open the door to a tighter integration between Model-Based Systems Engineering (MBSE) and Simulation Process and Data Management (SPDM). An SPDM platform can directly retrieve simulation requests as well as simulation model inputs from the SysML v2 system model, reducing manual handover and improving traceability and consistency between definition and simulation activities. This paper presents an approach for connecting SysML v2 and SPDM in order to support more agile and coherent development loops between systems engineering definition and simulation. Samares Engineering and Inensia illustrate this approach through the demonstration of an end-to-end iterative workflow.
