Hi There,
I am using the TriAxialStressController to compress a packing of particles. Once the compression is complete id like to get the size and origin of the volume
I found compressor.width / height / depth which i believe corresponds to the X/Y/Z length of the volume? What is width0/height0 and depth0?

However, how do I get the origin or center of this volume? 

many thanks in advance
Jesse


Code shown below:


%%%%%%%%%%%
	O.engines = [
	   ForceResetter(),
	   InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Box_Aabb()]),
	   InteractionLoop(
		  [Ig2_Sphere_Sphere_ScGeom(),Ig2_Box_Sphere_ScGeom()],
		  [Ip2_FrictMat_FrictMat_FrictPhys()],
		  [Law2_ScGeom_FrictPhys_CundallStrack()]
	   ),
	   TriaxialStressController(
		  thickness = 0,
		  stressMask = 7,
		  internalCompaction = False,
		  label = 'compressor',
	   ),
	   NewtonIntegrator(damping=.6),
	]
	factor = .5
	O.dt = factor * PWaveTimeStep()
	
	
	#print(compressor.height)
	compressor.goal1 = compressor.goal2 = compressor.goal3 = -1e-3
	#compressor.goal1 = compressor.goal2 = compressor.goal3 = -1e-5
	O.run(50000,True)
	print compressor.goal1
	print compressor.boxVolume
	
	print('width_x: ',compressor.width)
	print('height_y: ',compressor.height)
	print('depth_z: ',compressor.depth)
	print('width0_x: ',compressor.width0)
	print('height0_y: ',compressor.height0)
	print('depth0_z: ',compressor.depth0)
