The FMI Blockset User Interface (UI) enables the user to select and configure FMUs in Microsoft Excel. The FMI Blockset UI will extract and read the FMU and upload the required information in the FMU Setup Excel spreadsheet. In the FMI Blockset UI the user can edit values of Parameters, Constants & Variables and also edit initial conditions via the Initial Values tab.
