General questions about EMPHYSIS and eFMI
When will eFMI 1.0.0 be released?
EMPHYSIS partners have sent an application to the Modelica Association to form a Modelica Project eFMI. Once founded, the new eFMI group will try to quickly release the eFMI specification as Modelica Association standard. A concrete release date is not yet known.
What will be the license and usage conditions for the planned eFMI standard?
Access and use of the eFMI standard will be free of charge.
To be clear: While the eFMI standard will be open and free, commercial tool support might not be.
How is eFMI related to FMI?
-
eFMI has different packaging formats. The main packaging format is an FMU for Co-Simulation where the eFMI definition is stored under directory extra/org.efmi-standard and the FMU part is a wrapper around the selected Production Code representation.
This means that every FMI compliant tool supporting FMI for Co-Simulation can simulate the eFMU to perform Software-in-the-loop (SiL) testing. Code generation for an embedded device requires however dedicated tool support for eFMI. -
Technically, eFMI is using a few definitions from FMI 3.0, but otherwise can be seen as a complementary technology.
How is eFMI related to Modelica?
- Technically eFMI is not related to Modelica, and can be seen as a complementary technology.
- The intention of the eFMI project is to be neutral with respect to tools, technologies (e.g. solvers, OS, files, systems…) and languages (including Modelica).
- The eFMI standard shall be further developed as a Modelica Association Project within the Modelica Association, an organization focused on the “coordinated standardization and development of software technology and methods in the area of cyber physical- systems and systems engineering”, see the Modelica Association Bylaws and the History page
