Newly-developed automation with FMI Add-in for Excel streamlines the process of going from Modelica to a simulator in Excel.
The need for automation
We hear it all the time. Our customers want to do more model-based systems engineering. So that means more models deployed to more users…and preferably without more model developers and budget. Everyone wants more but how can we meet the demand? Cloning doesn’t seem like a viable option (unless you know something I don’t).
More automation and streamlined processes can help. With Modelica, we have an equation-based modeling language that provides great efficiency on the modeling side. The Functional Mockup Interface (FMI) provides even more ways to integrate and deploy models to users, even in non-traditional CAE environments. These two technologies offer the potential for enabling you to do more with less.
Dynamic simulation in Excel
Like it or not, Microsoft Excel is an engineering tool…because engineers use it. FMI Add-in for Excel brings the power of physical modeling into Microsoft Excel based on the FMI standard. The model developer can create models in a range of FMI-compliant tools and deploy those models as simulators in Excel. The simulators allow users to run simulations outside the native modeling environment, often without requiring licenses for the original development tools. Deploying models with Excel can also provide a less intimidating front end for running simulations.
With Modelica and the FMI Add-in for Excel, we can make both developers and users happy. Model developers can use best-in-class tools for building models and can deploy those models in a range of different tools using FMI. Users can run simulations and perform engineering analyses in familiar tools. See  for some recent work with Oak Ridge National Labs that combines the power of Modelica physical modeling in Dymola with deployment in Excel.
Automation with FMI Add-in for Excel
FMI Add-in for Excel is a flexible tool with a straight-forward workflow. Starting with a co-simulation FMU, you load the FMU, choose parameters and outputs to expose for simulation, create an experiment sheet for batch simulation, and run dynamic simulations in parallel using available cores on your machine. Standard post-processing is done with Excel.
