OMC Scripting

Dec-17-15 05:56:02

I tried this command

getParameterValue("BouncingBall","e")

on the BouncingBall model within share\doc\omc\testmodels:

model BouncingBall
  parameter Real e=0.7 "coefficient of restitution";
...


and I received this error message:

[<interactive>:1:1-1:0:writable] Error: Class getParameterValue not found in scope <global scope> (looking for a function or record).

According to this web page (https://build.openmodelica.org/Document … alue.html), the getParameterValue function should work. What did I miss? Any help would be greatly appreciated. Thanks.

BTW, loadModel(Modelica) and loadFile(getInstallationDirectoryPath()+"/share/doc/omc/testmodels/BouncingBall.mo") both returned true beforehand.

Best regards,
Axel

The doc is like this:

Code:


function getParameterValue

  input TypeName class_;

  input String parameterName;

  output String parameterValue;

end getParameterValue;

Which means you need to call it like this:

Code:


getParameterValue(BouncingBall,"e"); // no quotes for the first argument which is of TypeName

For more examples of the API you can have a look here:
https://github.com/OpenModelica/OpenMod … active-API
Begin with files interactive_*.mos

BTW, what do you want to do with the API?

Thanks for your help. I want to improve the SysML-Modelica transformation and make it work between OpenModelica 1.9.3 and MagicDraw 18.2 (https://github.com/SysMLModelicaIntegra … modelica).
