Hello Jesse,

They will always be 0,1,2,3,4,5 if the are the first bodies appended to
the simulation :-).

Cheers,

but as I said, I would not combine TriaxialStressController and O.periodic=True

Hi Jan,
Thank you, I see the periodic particles after adding the setBox and dimensions 
however I also get a runtime error:
FATAL /build/yadedaily-2016.06a-24-0557faf~xenial/core/ThreadRunner.cpp:30 run:

Do you know a way around this?

Hi,

I see all particles after:
O.periodic = True
O.cell.setBox(2e-6,2e-6,2e-6)

> I guess Peri3dController or PeriTriaxController?

I think so :-)

Hi Feng Chen,
Thanks for your answer. I'll try both options. Can I contact you after, by 
email, to describe the simulation of my master degree and How I can to execute 
the CFD-DEM coupling?

rhaven gave more information on the question:
Hi Jan,
I had only O.periodic=True
I added O.cell.setBox, but I dont see a difference. 

If TriaxialStressController is using walls for compression it guess it makes 
sense to use something else which can do periodic boundaries...
I guess Peri3dController or PeriTriaxController?

Hi,
do you just use O.periodic=True, or also O.cell.setBox? 
I am not very familiar with TriaxialStressController, but is uses walls for 
compression, so I would say using O.periodic=True does not make much sense..
cheers

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

Hi Jan,
Sorry I realize now that the code you provided doesnt create a periodic 
packing, and when I try to add 
O.periodic=True, all of a sudden there are no clumps at all!
do you know why this is happening?

Hello,
sorry for late answer. I have tried your script and could not reproduce your 
problem. The plates has nonzero force, i.e. it does apply forces on particles.
That the particles cross the plate is a matter of material law and parameters.
cheers
