FMI Standard

The FMI Standard and Its Significance in Industry

FMI as a means to accelerate product development

The Functional Mock-up Interface (FMI) standard is an open standard first released in 2010 as a solution for reducing integration efforts between simulation models and tools.

Since its release, the FMI standard has had a positive impact on industry. Simulation model providers and their customers have been able to improve and streamline the integration process. Moreover, the standard has enabled them to simplify model development, reduce tool development and tool management costs, and accelerate product development and iteration cycles.

FMI as a means to separate concerns

With FMI, simulation model providers and tool providers have the responsibility to comply with the standard. Customers are then free to focus on the development of their target products.

Greater flexibility comes with higher complexity

The FMI 3 standard notably expands on the application use cases compared to its predecessor version, the FMI 2 standard. It is composed of three interface types, approximately 70 function signatures, new data types, and new modes for state machines. In addition, new abstractions such as super-dense time and clock semantics are included.

With the significant increase in functionality, the complexity of ensuring that the required behaviors are being provided also increases. Furthermore, the potential associated costs also need to be considered.

In this regard, Fraunhofer IESE supports customers working with FMI 3 projects by supporting streamlining the development of Functional Mock-Up Units (FMU) with FMI 3. We can assist with the design, establishment, and monitoring of processes to reduce the development and deployment costs of new FMUs.

Significance of the FMI standard in industry – an overall context. Customers are interested in building products. When the need for simulation is determined, the Customer commissions Simulation Engineers. Simulation Engineers are responsible for the appropriate modeling of the product and its context. In addition, they may be responsible for part of the product performance assessment. To fulfill their tasks, a Simulation Engineer may consider the use of third-party simulation models. These can be provided as reusable FMUs, sold separately by various Simulation Model Providers. To execute the devised simulations, a simulation tool capable of importing FMI 3-compliant FMUs is required. Fraunhofer IESE in the position of the Simulation Tool Provider offers FERAL as the to-go solution.

Our virtual engineering solution

Fraunhofer IESE has been developing solutions for simulating arbitrary scenarios that require the inclusion of FMI 3 FMUs in a plug-and-play fashion. To this end, we envision the execution of arbitrary FMUs and simulation scenarios using our FERAL Framework. Our intention is to make this as easy as providing the FMU files and a simulation scenario setup.

FERAL is a powerful and efficient simulation toolset. It provides a framework for devising arbitrary simulation actors. Moreover, it includes ready- and easy-to-use bus simulation models to realize their communications.

We want to leverage the diversity of the market and empower all stakeholders. We do this by enabling the use of off-the-shelf simulation models developed by third parties. Additionally, FERAL’s support of the FMI 3 standard is in line with our objective of providing one of the most efficient and flexible simulation frameworks available.
