For this example I used OpenModelica 1.9.1 Beta2 (r19512)
And with the latest version I had the same error.

FMU Co-simulation : Inputs/Outputs of FMU Block

Category: Usage and Applications

Forum: OpenModelica Usage and Applications

Hello,
I have a problem with fmu co-simulation. The problem that there isn’t any call of fmiSetReal function from OpenModelica so that all of the input variables remain constant during simulation.
As I read from OpenModelica forum that (https://www.openmodelica.org/forum/defa … bles#p4313 ) currently OpenModelica doesn’t fully supports fmu co-simulation import.
However in this forum, Addel gives some solutions for fixing OpenModelica : he says that I can add SetReal function in the code. (https://www.openmodelica.org/forum/defa … bles#p4317 ).
I done this but I get another error : [:0:0-0:0] Error: Too many equations, over-determined system. The model has 4 equation(s) and 3 variable(s).
I would like to know if I need to add something special in order to fmiSetReal function will be called by OpenModelica or do you have another solutions for fmiSetReal function

Best regards,
Dimitri

Forum: OpenModelica development

Hello,

I have the problem with data exchange between fmu model and OpenModelica block. The FMU model I have built and imported from fmu sdk (https://www.qtronic.de/en/fmusdk.html)
The problem there isn’t any call of fmiSetReal function from OpenModelica so that all input variables remain constant during simulation. I also verified if others functions (example doStep, fmiGetReal etc) is called by OpenModelica and it is fine. All others function is called well by OpenModelica.
I would like to know if I need to add something special in order to fmiSetReal function will be called by OpenModelica.

Best regards,
Dimitri
