Hi Tuebel,
I'm not able to run the FmiWrapper_net on my system because of the System.AccessViolationException on the Instantiate method. I thank you for help.

Hi Tim,
I'm facing some issues with the FmiWrapper. The outputs of the function GetInteger seems to not working. I don't know if you could help me on that. I checked in Modellica and everything is ok.
But in C# the integer output never changes..

Thanks and Regards

Jules

Dear,

Below, you can find a piece of code that I use for instancing my models (build by AMESIM).
Why I'm able to load FMU: simple_multiplier3 and is FMU: Linked_Parameter_FMU not loading?

            // Create the instance
            string modelIdentifier = fmd.CoSimulation.modelIdentifier;
            string guid = fmd.guid.ToString();
            Console.WriteLine($"{modelIdentifier} - {guid}");

Linked_Parameter_FMU.zip
simple_multiplier3.zip

            using (var fmu = new FmuInstance(modelIdentifier + ".dll"))
            {
                // Setup
                fmu.Log += Fmu_Log;
                fmu.StepFinished += Fmu_StepFinished;
                fmu.Instantiate(modelIdentifier + "_Instance", Fmi2Type.fmi2CoSimulation, guid, "", false, true);
                Console.WriteLine("Types platform: " + fmu.GetTypesPlatform());
                Console.WriteLine("Version: " + fmu.GetVersion());
                fmu.SetupExperiment(false, 0, 0, true, 1000);
                fmu.EnterInitializationMode();
                fmu.ExitInitializationMode();


               // Simulate
                SimulateHEV(fmu);

                // Terminate the fmu
                fmu.Terminate();
            }

Hallo Tim,
ich kann mit dem FMU nur 2 maximal 3 male rechnen. ich bekomme die folgende Fehlermeldung (attached file

)

Danke für deine Rückmeldung
freundliche Grüßen

Hi Tuebel,
Now, I can use Co-Simulation's Model in my C# App by your wrapper.
And I want to use ModelExchange's Model, Does this wrapper support ModelExchange's model ?

Thanks.

i'm trying to solve a timeserie of numbers from -1000 till 1000, but get only errors:
Instance name: simple_multiplier_Instance, status: fmi2OK, category: debug, message: simple_multiplier_fmi2SetReal, #r134217728# = 1008.000000 (input variable 0)

input Real values: 1008

We use fmu.SetReal(setRealVr, setRealValues); and fmu.GetReal(getRealVr, getRealValues);

Thanks in advance,

Hi Tuebel,
I want to use the wrapper within my webApp (ASP.net), but the Instantiate method still Returns Zero.
I thank you for your help.

hello

we are using modelica and exorting the testdata BouncingBall (any would do) and getting error during initation:

assert | debug | Failed to open file (null)/BouncingBall_info.json for reading: No such file or directory
getBestJumpBuffer got mmc_jumper=0000000000000000, globalJumpBuffer=0000000000000000

the .fmu is loaded corrctly and is valid via fmu-checker:
FMI Version
2.0
FMI Type
Model Exchange, Co-Simulation
Model Name
BouncingBall

The file its crying about can be located in the fmu/resource
