v3.0

New features in FMI 3.0

• Array variables:
  Allow FMUs to communicate multi-dimensional variables and change their sizes using structural parameters.

• Clocks and Co-Simulation with events:
  Introduce clocks for synchronization of variable changes across FMUs and event mode in co-simulation.

• Binary Data Type:
  Adds an opaque binary data type to FMU variables to allow, for instance, efficiently exchanging of complex sensor data.

• Intermediate Variable Access:
  Allow access to intermediate input and output values between communication time points from the FMU to disclose relevant subsystem behavior for analysis or advanced co-simulation master algorithms for enhanced numerical stability.

• Source code FMUs:
  Provide a build description file to improve automatic import of source code FMUs.

• Numeric Variable Types:
  Adds 8, 16, 32 and 64-bit signed and unsigned integer and single precision floating point variable types to improve efficiency and type safety when importing / exporting models from the embedded, control and automotive domains.

• Extra directory:
  Adding a new folder in the ZIP Archive representing an FMU, providing additional data to travel with the FMU which can be modified by different tools, allowing for layered standards.

• Ports and Icons:
  Help the user to build consistent systems from FMUs and render the systems more intuitively with better representation of structured ports (for instance busses and physical connectors) in the modelDescription.xml.
