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.

1. Open a Julia-REPL, switch to package mode using ], activate your preferred environment.

2. Install FMIExport.jl:

(@v1) pkg> add FMIExport

3. If you want to check that everything works correctly, you can run the tests bundled with FMIExport.jl:

(@v1) pkg> test FMIExport

4. Have a look inside the examples folder.

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
• FMIBase.jl: Common concepts for import and export of FMUs
• FMICore.jl: C-code wrapper for the FMI-standard
• FMISensitivity.jl: Static and dynamic sensitivities over FMUs
• FMIBuild.jl: Compiler/Compilation dependencies for FMIExport.jl
• FMIFlux.jl: Machine Learning with FMUs
• FMIZoo.jl: A collection of testing and example FMUs

FMIExport.jl is tested (and testing) under Julia v1.6 (LTS) and v1 (latest) on Windows latest. x64 architectures are tested. Ubuntu is under development and near completion.

• 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 with fmiCreate can be used in FMI.jl without the need to export and re-import it, the FMU behaves like any other FMU loaded via fmiLoad.
