FMI.jl

What is FMI.jl?

FMI.jl is a free-to-use software library for the Julia programming language which integrates FMI (fmi-standard.org): load, instantiate, parameterize and simulate FMUs seamlessly inside the Julia programming language!

How can I use FMI.jl?

open a Julia-Command-Window, activate your prefered environment
goto package manager using ]
type add FMI or add "https://github.com/ThummeTo/FMI.jl"
have a look inside the example folder

How can I simulate a FMU and plot values?

# load and instantiate a FMU
myFMU = fmiLoad(pathToFMU)
fmiInstantiate!(myFMU)

# simulate from t=0.0s until t=10.0s and record the FMU variable named "mass.s"
simData = fmiSimulate(myFMU, 0.0, 10.0; recordValues=["mass.s"])

# plot it!
fmiPlot(simData)

# free memory
fmiUnload(myFMU)

What is currently supported in FMI.jl?

the full FMI command set, including optional specials like getState, setState and getDirectionalDerivative
parameterization, simulation & plotting of CS- and ME-FMUs
event-handling for discontinuous ME-FMUs
...

What is under development in FMI.jl?

FMI 3.0 and SSP 1.0 support
FMI Cross Checks
more examples
...

What Platforms are supported?

FMI.jl is tested (and testing) under Julia Version 1.6 and latest on Windows (latest) and Ubuntu (latest). Mac should work, but untested.
