Dymola 2013 FD01 Release notes 43
All mandatory features are supported in FMI 2.0 Beta 4. The optional (in the sense that they
have associated capability flags) features not supported are:
• FMUs can only be instantiated once per process.
• The internal FMU state cannot be serialized.
• Estimates of output derivatives are not provided.
• fmiDoStep cannot run asynchronously.
The
Files > Import > FMU… commands and script function importFMU accepts FMUs
created according to FMI 2.0 Beta 4 Model Exchange specification. Current supported
features are the same as for FMI 1.0.
3.6 Advanced Modelica Support
3.6.1 Synchronous Modelica and State Machines (LA)
The synchronous features and state machines of Modelica 3.3 have Limited Availability
(LA) support since the specification in Modelica 3.3 has been finished only recently. The
features are enabled by the scripting command
Advanced.Synchronous = true.
References to papers describing these features, and a tutorial presentation, are available
using the command
Help > Documentation. A tutorial is also available using the command
Help > Demos > Synchronous Tutorial. The tutorial relates to the papers and presentation
mentioned.
