If ComputeHeat.c is in the same folder as the containing model you can use:

modelica://CurrentModelName/ComputeHeat.c

I made a custom Modelica Library the other day wich contains code written in c/c++. That code is being compiled by clang to a .dll and .a (openmodelica 1.17).

The Librarys file tree now looks like this:

MyLib

│   package.mo

│

├───SomeFolder

│       SomeModel.mo

│       SomeOtherModel.mo

│       package.mo

│       package.order

│

└───Resources

    ├───Include

    │       SomeModelHeader.h

    │       SomeOtherModelHeader.h

    │

    └───Library

        └───mingw64

                libSomeLibrary.dll.a

                SomeLibrary.dll

The library functions are accessed via ExternalObject / extern "C"

within MyLib.SomeFolder;

type SomeModel

  extends ExternalObject;

  function constructor "Instantiate Classes and allocate Memory"

    output SomeModel someModel;

    external "C" someModel = initSomeModel()

    annotation(

      Library = "SomeLibrary",

      Include = "#include \"SomeModelHeader.h\"");

  end constructor;

  function destructor "Release Class instances and Memory"

    input  SomeModel someModel;

    external "C" closeSomeModel(someModel);

  end destructor;

end SomeModel;

When i compile a model using this, the simulation process crashes, because it's not able to find SomeLibrary.dll.
If i manually copy the dll to c:\Users\myUserAppData\Local\Temp\OpenModelica\OMEdit\MyModel simulation works as expected.

Questions:
- Is it possible to add the Resources/Library/mingw64 to the dll search path for the simulation executable
- Is it possible to force openmodellica to do static linking, which would avoid the previous issue.

The Libraries shipped with openmodelica use __iti_dll/__iti_dllNoExport in 'external "C"', but the usage is not documented.

Any hints welcome!

Hello!

Imagine the following SImulation Results

Boolean myBool, with values 0 and 1, e.G. from a switch or thyristor or similar.
Voltage myVoltage, with values 0..400A

On that plot you can hardly see the Boolean. Is there a way to scale boolean values or put them on a second y axis?

Unfortunately uploading images to the forum seems to be broken, gives "0 Class 'JvitalsHelper' not found "

Thanks & Regards,
