Functional Mock-up Interface

FMI allows any modeling tool to generate C code or binaries representing a dynamic system model which may then be seamlessly integrated in another modeling and simulation environment.

FMI Support in Dymola


FMI 2.0 support

FMI 2.0 (released on July 25, 2014) has been supported in Dymola since the Dymola 2015 FD01 release on both Windows and Linux. Please consult the Dymola Release Notes and User's Manual for details on support of optional FMI features.
