Question #655521 on Yade changed: https://answers.launchpad.net/yade/+question/655521 rhaven posted a new comment: Hi Robert, thank you for your reply. I was able to get the bottom corner of the volume using: x = min(O.bodies[0].state.pos[0],O.bodies[1].state.pos[0]) y = min(O.bodies[2].state.pos[1],O.bodies[3].state.pos[1]) z = min(O.bodies[4].state.pos[2],O.bodies[5].state.pos[2]) in my case I know the wallIds because I generate walls in a previous step, but i guess ids 0,1,2,3,4,5 might not always be the walls.. thanks Jesse -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

Question #655521 on Yade changed: https://answers.launchpad.net/yade/+question/655521 Status: Open => Answered Robert Caulk proposed the following answer: Hello, I think you are right, X/Y/Z = width/height/depth [1]. height0 is the reference height used for strain calculation [2]. >However, how do I get the origin or center of this volume? So you want the center of the box defined by the locations of the triaxial walls? The user defines the geometry and position of the walls explicitly. In most triaxial loading conditions, the center should not change. If for some reason you are expecting unsymmetric deformation or specimen translation, you can you use the position of the walls to determine where the center is. O.bodies[1].state.pos provides access to this information.

[Yade-users] [Question #655521]: using TriAxialstressController obtain volume origin and size
New question #655521 on Yade:
https://answers.launchpad.net/yade/+question/655521
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(5,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)
