Modelica3D Visualization

Jul-16-15 22:28:20

Hello,

I am trying to use Modelica3D but no visualization window pops up after simulating the model. I am using the users guide for release v1.9.3-dev.520+g2b2d98c.

I have installed
Python version 2.7.10
pygtk-all-in-one-2.24.2.win32-py2.7.msi
openModelica "v1.9.3-dev-1091-gb25d1f3"

To start I open cmd and browse to the directory containing dbus-server.py

Code:

 > cd C:\OpenModelica1.9.3Nightly\lib\omlibrary-modelica3d\osg-gtk

I then run the script and see the "Running dbus-server..." notification.

Code:

> python .\dbus-server.py

     Running dbus-server...

At this point i open OMShell and enter the following, with the result:

Code:

>> loadModelica3D();



>> getErrorString()

""



>> loadString("model DoublePendulum

 extends Modelica.Mechanics.MultiBody.Examples.Elementary.DoublePendulum;

 inner ModelicaServices.Modelica3D.Controller m3d_control;

end DoublePendulum;")

true



>> getErrorString()

""



>> simulate(DoublePendulum)

As far as I can tell the simulation is working, but there is no visualization window that appears. I assume I am missing a step?
Any help would be appreciated.
Thanks!

Hi,

This seems to be a bug newly introduced. I suggest you try an older nighly build:
https://build.openmodelica.org/omc/buil … lds/older/
from beginning of June.

I opened a bug ticket about this and I'll debug a bit more:
https://trac.openmodelica.org/OpenModelica/ticket/3385
and hopefully fix it soon.

Cheers,
Adrian Pop/
