FMIExport.jl
What is FMIExport.jl?
FMIExport.jl is a free-to-use software library for the Julia programming language which allows for the export of FMUs (fmi-standard.org) from any Julia-Code. FMIExport.jl is completely integrated into FMI.jl.
How can I use FMIExport.jl?
1. Open a Julia-REPL, switch to package mode using ]
, activate your preferred environment.
2. Install FMIExport.jl:
(@v1.x) pkg> add FMIExport
3. If you want to check that everything works correctly, you can run the tests bundled with FMIExport.jl:
(@v1.x) pkg> test FMIExport
4. Have a look inside the examples folder in the examples branch or the examples section of the documentation. All examples are available as Julia-Script (.jl), Jupyter-Notebook (.ipynb) and Markdown (.md).
What FMI.jl-Library should I use?
To keep dependencies nice and clean, the original package FMI.jl had been split into new packages:
- FMI.jl: High level loading, manipulating, saving or building entire FMUs from scratch
- FMIImport.jl: Importing FMUs into Julia
- FMIExport.jl: Exporting stand-alone FMUs from Julia Code
- FMICore.jl: C-code wrapper for the FMI-standard
- FMIBuild.jl: Compiler/Compilation dependencies for FMIExport.jl
- FMIFlux.jl: Machine Learning with FMUs (differentiation over FMUs)
- FMIZoo.jl: A collection of testing and example FMUs
What Platforms are supported?
FMIExport.jl is tested (and testing) under Julia Versions 1.6.6 LTS and latest on Windows latest. x64
architectures are tested. Ubuntu is under development and near completion.
Known limitations
- Currently it is not possible to hold more than one sysimg in a Julia session, so it is not possible to load FMUs generated with FMIExport.jl into FMI.jl using
fmiLoad(...)
. However, FMUs created withfmiCreate
can be used in FMI.jl without the need to export and re-import it, the FMU behaves like any other FMU loaded viafmiLoad
.
