Example problem, or to create a function ?

Hi, could you, please, _attach_ the script instead of putting it into
the message?

Thanks.

I think the problem in your code is in indention. It should look like this:

def addPlotData():
  plot.addData(i=O.iter,unbalanced=utils.unbalancedForce(),**O.energy)

and

def checkUnbalanced():
  if utils.unbalancedForce()<.05:
  O.pause()
  plot.saveDataTxt('bbb.txt.bz2')

"Hi, could you, please, _attach_ the script instead of putting it into
the message?"

Here is the link of the script http://www.2shared.com/file/xrflYnqC/Tuto2.html (how can I attach the script otherwise ?).
Is it important to define the function before/after the O.engines ?

"I think the problem in your code is in indention"
It's true I didn't know that the indentation was important with Python, but it is. But I still have the problem, "NameError: name 'addPlotData' is not defined".

Strange, your script on Ubuntu 10.04 and with yade r2813 is working:

yade.plot:

Just one problem: utils.facetBox should be replaced by geom.facetBox.
But it is not critical.
Let us know, if you still has a problem.

You are right, there is no way to attach a file to answers, sorry for
wrong suggestion...

Still the problem, did I forget to import some things ? (such as "from yade import plot, pack, geom, utils").

This question was expired because it remained in the 'Open' state without activity for the last 15 days.
