Technical Support

FMI Composer 1.1 is part of Modelon’s 2018.2 release.

FMI Composer is a tool for handling systems of FMUs, described according to the SSP standard. SSP systems can be graphically created and edited, and systems can also be exported as a single aggregated FMU for use in other tools.

In addition to system editing and aggregation, FMI Composer can also modify FMUs in the following ways:

• Remove non-essential information to protect sensitive details in the model.
• Override parameters and start values in the original FMU.
• Convert ME FMUs to CS FMUs by attaching an ODE solver.

All operations except editing are performed during FMU export, and they can be combined as needed.

New features

• Constant block
• Source block FMUs
• Support for parameter promotion. It is now possible to add system level parameters and map to FMU parameters, constants, and system inputs.
• Parameterization of system inputs

Enhancements

• Improvements to the group connections dialog have been done. Automatic connections were added and general enhancements such as filtering capabilities, tooltips, and color indicators for connected signals.
• SSP Standard version updated from “Draft20170606” to “Draft20171219”.
• SSP files saved using the old form will automatically be upgraded to the newer version when opened.
• The flag canBeInstantiatedOnlyOnce is now set to true in aggregated FMUs.
• Fixed issue with exported zip-files not being compatible with java input-streams in some cases.
• Improved logging so that it is possible to identify which sub-FMU failed.
• Other minor improvements and bug fixes.
