FMI Add-In for Excel - Release Information


  • Fixed FMI Add-In for Excel to not require MSVCR100D.dll


  • Added FMI Add-In for Excel installer for 64-bit Excel.
  • Removed data validation with drop-down menu for boolean values.


  • Fixed bug with missing FMIAddInScript.xlsm.


  • Simulation or initialization is now performed with current directory set to the workbook directory. This should
    simplify the look up of external data in the FMU, that relays on current directory. The workbook must now
    always be saved before any simulation or initialization is run.
  • Temporarily tries to unprotect a protected experiment sheet before a simulation or initialization is run, and before
    the workbook is saved.


  • Updated installer to not require running in elevated mode unless any of the prerequisites is missing and requires elevated mode to be installed.
  • Fixed bug with locale dependent expiry date.
  • Fixed bugs in the updating script and in loading invalid FMUs.
  • Simulation results now includes the result point at initial time.


  • Introduced new license feature: runtime (FMI_ADDIN_EXCEL_RUNTIME). With this license feature, users can perform simulations, parameter sweeps, etc and use a restricted set of the API macro functions. For more information, see Section 5.2 in Chapter 2.
  • Introduced possibility to set an experiment expiry date.
  • Changed license checkout procedure. The license will now be checked out when the user starts working with FMI Add-In for Excel, rather than at startup of Excel.


  • Fixed problem with loading FMUs containing external DLL files. 


  • Support for calling the add-in functions from Visual Basic script in Excel.
  • Simulation timeout time can now be specified for each case in the Experiment sheet. 


  • Fixed problem with parsing input trajectory values.
  • Fixed problem with long simulations causing Excel to display the dialog message: Excel is waiting for another application to complete an OLE action. 


  • Changed simulation timeout time from 100s to infinity


  • Parallel simulation and initialization support
  • Excel sheets based on named ranges
  • The FMU path in the Experiment sheet can be an absolute path or relative path
  • New example added, a heat exchanger for steady-state computation that uses the initialization functionality to perform a parameter sweep


  • FMI Add-In is built with FMI Library 2.0a2 containing bug fixes


  • Simulation of Co-Simulation 1.0 FMUs supported
  • Initialization of Model Exchange 1.0 FMUs supported
  • Input trajectories supported
  • Final simulation and initialization results are written to an experiment sheet
  • Simulation of Co-Simulation FMUs generates a result sheet with output trajectories
