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?

1. open a Julia-Command-Window, activate your prefered environment
2. goto package manager using ]
3. type add FMI or add "https://github.com/ThummeTo/FMI.jl"
4. 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?
