Introduction

In an era where system-level design and simulation are critical to innovation, the Functional Mockup Interface (FMI) has emerged as a key standard for model exchange and co-simulation. Developed under the Modelica Association, FMI enables seamless integration of simulation models from diverse tools, fostering collaboration across disciplines. As digital twins gain prominence, tools like Twin Simulate are leveraging FMI to create robust, multi-domain simulation environments. Watch the accompanying video to see how easy it is to import an FMU into Twin Simulate for a system simulation model.

What is Functional Mockup Interface (FMI)?
FMI is an open standard for exchanging and co-simulating dynamic models through Functional Mockup Units (FMUs)—encapsulated files containing model equations, data, and simulation capabilities. Many leading simulation tools support FMI, including Dymola, OpenModelica, AMESim, and SimulationX to name a few. For an exhaustive list of tools one can visit the fmi tools section in the FMI website . This interoperability makes FMI a critical enabler for multi-domain system simulations.

Twin Simulate: Empowering Digital Twin Simulations with FMI
Twin Simulate simplifies the integration of FMUs into its platform, allowing engineers to:

• Import and Integrate FMUs: Seamlessly import FMUs from various tools and assemble system-level simulations. Check out the video demonstration to see the process in action.
• Enable Multi-Domain Simulations: Synchronize models from different domains, such as mechanical, electrical, and thermal, for accurate co-simulation.
• Support Scalable Modeling: Build progressively complex system simulations by integrating additional FMUs.
• Facilitate Real-Time Analysis: Perform real-time simulations to validate designs and test scenarios with high fidelity.

Here is a demo video of the overall process . We are looking forward for what use cases our users would build with such capabilities.

Conclusion
FMI is revolutionizing engineering simulations by fostering flexibility and interoperability across tools. With its extensive support for FMI, Twin Simulate empowers engineers to build scalable, multi-domain digital twins efficiently. Ready to unlock the power of FMI in your projects?
