The leading standard to exchange dynamic simulation models
The Functional Mock-up Interface is a free standard that defines a container and an interface to exchange dynamic simulation models using a combination of XML files, binaries and C code, distributed as a ZIP file. It is supported by 200+ tools and maintained as a Modelica Association Project.
Layered Standards
The following Layered Standards based on FMI are currently under development.
Getting started
Jupyter notebooks are a great way to work with FMUs. Join us for an interactive tour of the FMI.
open on Google Colab or Binder
Implement the FMI
The Reference FMUs are a free reference implementation of both FMI import and export and a starting point for development, testing and debugging.

What users say about FMI:
"FMI is the preferred model exchange and co-simulation format of Robert Bosch GmbH at system level enabling the exchange of models with internal and external partners using different modelling tools."
"Driving our future is all about scalable solutions. The use of the FMI standard scales our capabilities to virtual integrate our scalable braking systems with customers’ and partners’ systems of systems."
"Supported by Siemens from the beginning, FMI is becoming an important building block in the efficient creation of interdisciplinary, multi-level digital twins of our entire portfolio - from rail and gas turbine engineering to virtual commissioning in the process industry and operational support in manufacturing plants."
"With the ever increasing use of models in aircraft system development, tool interoperability and model reuse are central challenges. At Saab we see the FMI standard as an enabler for scalable and tool neutral integration of simulation models from different technical disciplines, developed by different internal teams or by external partners."
