Hi!

I also have problems when trying to obtain animations using modelica3D and OMShell.

I have followed the instructions given by the User Guide and clearly explained by Sanjay_Kamath in this post. Although everything seems to be ok, some errors appear when typing the commands in OMShell.

First of all, I would like to highlight that the following warning appears when typing loadModelica3D():
Warning: Requested package ModelicaServices of version 3.2.1, but this package was already loaded with version 3.2.1 modelica3d. You might experience problems if these versions are incompatible.

I don't know if this is the responsible of the error I get when trying to compile the model and obtain the animation:
loadModelica3D();
loadString("model visualizemodel
  extends Modelica.Mechanics.MultiBody.Examples.Elementary.DoublePendulum;
  inner ModelicaServices.Modelica3D.Controller m3d_control;
end visualizemodel;"); getErrorString();
simulate(visualizemodel, startTime=0.0,stopTime=10.0);

Can you help me with that, please? I'm using OpenModelica 1.9.1 and I installed the recommended versions of Python and pyGTK.

Thank you,
