we are consulting multiple customers on application and introduction of PTC Windchill Modeler and want to use system models as basis for physical simulation models in Simulink.
It is common practice to extend the standard SysML Stereotypes to company-specific Stereotypes (e.g. for creating a RFLT-hierarchy by deriving a "funcional block" or "logical block" from the standard SysML Block, see attached picture). The Simulink Synchronizer (in version 9.5) only recognizes standard SysML Blocks as elements for synchronization and will ignore blocks with such custom stereotypes.
This restriction will lead our customers to reconsider the decision to introduce the Windchill Modeler.
Thank you for consideration. Johannes Krautkremer, :em engineering methods AG
