save spheres packing

 

Hi,
I would like to let my spheres' packing arrange under gravity acceleration, and save the spheres position after that (by fixing a kineticEnergy threshold). The yade.pack.SpherePack.save('..') function doesn't help me, it saves the positions of spheres initially generated, the original cloud.
I didn't find anything else that could help me in yade modules, am I wrong?

TriaxialCompressionEngine uses Shop::saveSpheresToFile to do what I need.
How can I access that function from python?

thanks, Ema.
