Issue with FMU Export after Manipulating Model in Julia

General Usage

Hi everyone,

I am trying to export an FMU in Julia after importing and manipulating an FMU model. Specifically, I followed the example for manipulation from the documentation of FMIExport.jl, which can be found here:

Manipulation Example

The code works fine up to the following point:

using FMI
using FMIExport
using FMICore
using FMIZoo

originalGetReal = nothing # function pointer to the original fmi2GetReal c-function

function myGetReal!(c::fmi2Component, vr::Union{Array{fmi2ValueReference}, Ptr{fmi2ValueReference}}, nvr::Csize_t, value::Union{Array{fmi2Real}, Ptr{fmi2Real}})
    global originalGetReal
    status = fmi2GetReal!(originalGetReal, c, vr, nvr, value)
    
    if isa(value, Ptr{fmi2Real})
        value = unsafe_wrap(Array{fmi2Real}, value, nvr, own=false)
    end
    if isa(vr, Ptr{fmi2Real})
        vr = unsafe_wrap(Array{fmi2Real}, vr, nvr, own=false)
    end
    
    for i in 1:nvr 
        if vr[i] == 335544320 # value reference for "positionSensor.s"
            value[i] *= 2.0 
        end
    end

    return status
end

FMIBUILD_CONSTRUCTOR = function(resPath)
    global originalGetReal
    fmu = loadFMU(joinpath(resPath, "SpringDamperPendulum1D.fmu"))
    originalGetReal = fmu.cGetReal
    fmi2SetFctGetReal(fmu, myGetReal!)
    return fmu
end

This generates the necessary files including binaries, documentation, source, and model description (XML). However, I am having trouble exporting it into a single .fmu file. I tried using the following code:

using FMIBuild
FMIBuild.saveFMU(fmu, fmu_save_path)

But it throws the following warnings and error:

β”Œ Warning: This FMU has a model name `SpringDamperPendulum1D` that does not fit the FMU filename `Manipulation.fmu`. Is this intended?
β”Œ Warning: This FMU has a model exchange identifier `SpringDamperPendulum1D` that does not fit the FMU filename `Manipulation.fmu`. Is this intended?
β”Œ Warning: This FMU has a co simulation identifier `SpringDamperPendulum1D` that does not fit the FMU filename `Manipulation.fmu`. Is this intended?
ERROR: AssertionError: ["fmiBuild(...): Cannot find a package where this file is stored in. For FMU-Export, this source file needs to be inside of a package."]

Can anyone shed light on what I might be doing wrong or whether you have faced similar issues?
Looking forward to your responses. Thanks!

If you take a close look at the BouncingBall example in the github repository, you can see that it’s not just a julia code, but actually a package with its own Project.toml. I guess the build process requires your code to be inside a package, something you’d expect when there’s PackageCompiler running under the hood.

Generate a dummy package & add the required dependencies, replace its src/something.jl with your (or the example) code, and it will work.

Edit) The generated package’s name should match the designated fmu file name(e.g. if the package name is BouncingBall, the fmu file name in fmu_save_path should be BouncingBall.fmu ), otherwise it’ll cause an error during the process.

Exactly!

FMUs are not compiled form files, but from packages. This way you can control, which dependencies you compile in (because binary sizes are pretty large for now). So a good starting point for a new FMU export is copying the entire demo-project (in this case the β€œManipulation” folder).

In future you can tag me, so I can answer more fast.

Thanks a lot for the advice earlier @ThummeTo & @littlelib , it was really informative!

As suggested, I attempted to place my code within a Julia package. Below is the workflow I followed. Since I’m a newbie here, I have shared all in detail. While it seems to work better now and does build something, I still run into an error at the end. I’ve included both the workflow and the results.

I would greatly appreciate any help in fixing the error and successfully saving the FMU file!

Step 1: Create a New Julia Package

using Pkg
Pkg.generate("FMUManipulation")

Navigate to the package directory:

cd FMUManipulation

Step 2: Update Project.toml

using Pkg
Pkg.add("FMI")
Pkg.add("FMIExport")
Pkg.add("FMICore")
Pkg.add("FMIZoo")
Pkg.add("FMIBuild")

Step 3: Replace Code in src/FMUManipulation.jl

Open src/FMUManipulation.jl and replace its contents with your manipulation code. Here’s what I used:

module FMUManipulation

using FMI
using FMIExport
using FMICore
using FMIZoo
using FMIBuild

originalGetReal = nothing # function pointer to the original fmi2GetReal c-function

function myGetReal!(c::fmi2Component, vr::Union{Array{fmi2ValueReference}, Ptr{fmi2ValueReference}}, nvr::Csize_t, value::Union{Array{fmi2Real}, Ptr{fmi2Real}})
    global originalGetReal
    status = fmi2GetReal!(originalGetReal, c, vr, nvr, value)
    
    if isa(value, Ptr{fmi2Real})
        value = unsafe_wrap(Array{fmi2Real}, value, nvr, own=false)
    end
    if isa(vr, Ptr{fmi2Real})
        vr = unsafe_wrap(Array{fmi2Real}, vr, nvr, own=false)
    end
    
    for i in 1:nvr
        if vr[i] == 335544320 # value reference for "positionSensor.s"
            value[i] *= 2.0
        end
    end

    return status
end

function FMIBUILD_CONSTRUCTOR(resPath)
    global originalGetReal
    fmu = loadFMU(joinpath(resPath, "SpringDamperPendulum1D.fmu"))
    originalGetReal = fmu.cGetReal
    fmi2SetFctGetReal(fmu, myGetReal!)
    return fmu
end

function save_my_fmu(fmu_save_path)
    FMIBuild.saveFMU(fmu, fmu_save_path)
end

end # module FMUManipulation

Step 4: Test Your Package

In the Julia REPL, I activated the new package and tested the FMU manipulation:

using Pkg
Pkg.activate("path/to/FMUManipulation")

using FMUManipulation
using FMIZoo
using FMIBuild

# Get the path to the SpringDamperPendulum1D FMU from FMIZoo
sourceFMU = FMIZoo.get_model_filename("SpringDamperPendulum1D", "Dymola", "2022x")

# Load and manipulate the FMU using the directory containing the FMU file
fmu = FMUManipulation.FMIBUILD_CONSTRUCTOR(dirname(sourceFMU))

# Specify the path where you want to save the modified FMU
fmu_save_path = joinpath(pwd(), "Manipulation.fmu")

# Save the modified FMU
FMUManipulation.save_my_fmu(fmu_save_path)

However, this last line of code throws error. Sorry I know the error log is quite big enough… but any how I hope it would help!

My guess is that there might be some conflicting dependencies. Could that be the case, or is it something else? Any help would be greatly appreciated!

Sorry for the late reply.

The main problem of your code seems to stem from step 3 and 4.

You shouldn’t put your code in a module.
I know it doesn’t sound right, but your FMUManipulation.jl file will not be directly executed - it’ll be read by FMIBuild.jl, manipulated, and recreated as a proper package somewhere in your dedisgnated location.
Although I also don’t know how it works in detail, following the codes in the examples seems to work fine, like putting the build related code inside ### FMIBUILD_NO_EXPORT_BEGIN ### and ### FMIBUILD_NO_EXPORT_END ###.

It’ll be for the best you put build related codes inside the FMUManipulation.jl file, wrapped around in ### FMIBUILD_NO_EXPORT_BEGIN ### and ### FMIBUILD_NO_EXPORT_END ###, and simply do this:

$ julia --project=path_to_project path_to_project/src/FMUManipulation.jl

Although I couldn’t run the code you posted, official examples like BouncingBall compiled without error on my machine (Windows 11, Julia 1.11) this way. I think you should also start from the official examples, and don’t stray too far from it.

Exactly as @CurioMath stated!

We will do a more detailed tutorial for this soon, we are currently on refactoring the documentation.
