fullRobot Model

Dec-01-11 00:59:12

Hi!

I wanted to simulate the fullRobot and oneAxis Model from the library.
After half an hour of compiling and simulating, I came to the Plotting Area for the oneAxis Model, but there wasn't anything to select and plot..
Then I tried to simulate the fullRobot Model, but after nearly an hour of compiling and simulating I cancelled it with no output at all...
Took simply too long.
Anyone with the same probloms or can anyone help me?

I'm using OMEdit 1.8

Thanks, Fabian

Hi,

There's definitely something strange with the model simulation.
From what I can see from OMEdit logs it takes: 279.89 secs (4.6 minutes) to build the model (about 1 minute to run gcc).
Seems our back-end is a bit slow as it only takes 5.6 seconds to flatten the model (i.e. via instantiateModel(...)).
buildModel(Modelica.Mechanics.MultiBody.Examples.Systems.RobotR3.fullRobot,startTime=0.0, stopTime=2.0, numberOfIntervals=500, method="dassl", tolerance=0.000001, outputFormat="mat") 23:43:34:465
{"C:/Users/adrpo/AppData/Local/Temp/OpenModelica/OMEdit/Modelica.Mechanics.MultiBody.Examples.Systems.RobotR3.fullRobot","Modelica.Mechanics.MultiBody.Examples.Systems.RobotR3.fullRobot_init.xml"} 23:48:14:355
Elapsed Time :: 279.89 secs

Then it starts the executable which doesn't seem to progress at all.
Seems it gets stuck at initialization (I ran the executable from the command line with debug flags)
Modelica.Mechanics.MultiBody.Examples.Systems.RobotR3.fullRobot.exe -lv LOG_DEBUG
.....
info    | nelderMeadEx_initialization | initialization-nr. 0
and here it gets stuck. I'll add this as a bug so we can look at it.

Cheers,

I now added bug:

about this.
