problem with PyRunner when importing Yade in python

Hi Alexander,
try to call specific object, like

command="mySim.storeData()"

if this does not work, add

import __builtin__
__builtin__.mySim = mySim

after you create mySim

If nothing of this works, let us know :-)

cheers

Thanks. this works.

   command="mySim.storeData()"
is sufficient if you create the object of the class in which yade is used in the file of the class as it is shown in my code above.

the second solution:
   import __builtin__
   __builtin__.mySim = mySim
is necessary if you work with diffrent files in your programm.
In my case there is a main program that handles an optimisation algorithm which passes simulation parameters to the MyYadeSim class. (the object of MyYadeSim in the main programm is named mySim)

I could add an example script somewhere if you like

Would be nice!
Importing yade is sometimes tricky. We may add an example/importingYade
folder to collect a few examples. It would certainly help.
