FMI Add-in for Excel

The Functional Mock-up Interface (FMI) is an open standard for model exchange and co-simulation of dynamic models on the system and component level. FMI addresses a critical pain point in model-based systems engineering: the ability to share models between tools, and to deploy models in an easy-to-use way to development engineers. FMI is supported by more than 60 commercial simulation tools.

The FMI Add-In for Excel® provides powerful support for FMI in Microsoft Excel. FMI Add-In enables efficient and customizable analysis model-based workflows in a spread-sheet environment, with all data management and visualization capabilities of Microsoft Excel and Visual Basic at hand.

FMI defines the Functional Mock-up Unit (FMU) executable model format. FMUs may contain functional models like control algorithms as well as physical plant models. FMI thereby acts as a bridge to use Microsoft Excel® as an analysis and automation environment in model-based development workflows, such as performance optimization, sizing, robust design, and control system tuning. The FMI Add-In for Excel® in combination with Modelica model libraries accelerates the model-based development process by focusing engineering efforts on core product development activities rather than modeling tasks.


  • Allows users to exploit state-of-the-art physical modeling tools within an easy-to-access Microsoft Excel® environment
  • Enables parameter sweeps and sensitivity analysis that can provide insights into the impact of component variation on system behavior early in the design cycle
  • Provides simulation results within standard Excel spreadsheets, enabling organizations to quickly and easily exchange information among all shareholders in the enterprise
  • Maintains flexibility and consistency through the FMI standard.

Key Features

  • Import and simulation of Functional Mock-up Units (FMUs) in Microsoft Excel®
  • Parameter sweeps and sensitivity analysis
  • Parallel computations on multi-core platforms
  • Batch simulation and design space exploration
  • Supports FMI for Model Exchange 1.0 (initialization of models)
  • Supports FMI for Co-Simulation 1.0 (initialization and dynamic simulation)
