Giulia Macaro is still having a problem:
I'm using 3036, but I've commented the 'if(scene->Periodic)' condition in the
Bo1_ChainedCylinder_Aabb (line 328).
I'm sending you my script.
1. Thanks for the detailed explanation. The example of the sphere on the
inclined plane is quite useful.
But how many cells are reproduced during the simulation? Is it an infinite
number? I assume that, if I have a sphere falling under gravity inside a
periodic cell without any plane, it keeps on going out and in the primary cell,
in loop for ever, is that right?
2. I've run some more tests, and now it works fine with a large number of
chains (Ne=30 in generatePipe() of my script) and blocking the rotations and
lat translations.
If then I make the cylinder with only one chain (Ne=1), and still block xXYZ,
the cylinder doesn't move (as expected). Plus it seems to be periodic only on
one side.
If I remove the constrain to the DOFs, and make the cylinder with only one
chain, I've Segmentation Fault.
Could I just use the long chain with blockDOFs='xXYZ'? The cylinder seems to
behave still dynamically..
3. Is there any difference between creating a periodic cell (O.periodic=True
and O.cell.setBox()) and creating a periodic packing
(particleSD(periodic=True))?
My script works fine with O.periodic=True and particleSD(periodic=False), but
gives weird behaviour when also particleSD(periodic=True).
4. In the periodicSandPile example, it's not clear to me why the bottom
floor is not periodic. In my simulation I always have a periodic bottom
floor, and so the cylinder. How do I make them non-periodic?
Thank you
