Ruidong LI gave more information on the question:
Karol, Thanks for your reply.
---I think that you need to be much more specific. For example, is each of the
800 gts files modelling a single particle?
---Yes. Each GTS file denotes one single particle.
---Do you try to reproduce the exact shape of the sample (particles in their
corresponding locations from the very beginning)? What code do you use to
generate clumps?
---Yes. I'd like to reproduce the exact shape of the sample (particles in their
corresponding locations from the very beginning). The code I used to generate
the clump is presented below:
def createSphere(pred, ndivmin, spacing):
aabb = pred.aabb()
dim0 = aabb[1][0] - aabb[0][0]
bodyList = []
ndiv = ndivmin
while len(bodyList)==0:
radius = dim0 / ndiv # get some characteristic dimension, use
it for radius
bodyList = O.bodies.append(pack.regularHexa(pred, radius =
radius, gap = -radius, color =
[random.random(),random.random(),random.random()], material = sphereMat))
ndiv = ndiv + spacing
---Can you prepare the MVE[1]? If not possible, please describe your workflow.
--- I can provide the MVE. But I don't know how to provide my GTS. I just
imported gts files into Yade and created the surface, then generate spheres
using the 'pack.regularHexa' function.
---What do you mean that the sample shrinks in the height direction? Smaller
than expected after deposition, or did something actually shrink?
--- This means that when the unbalanced force ratio tends to be stable, the
height of the sample is smaller than the real value. The reason behind this, I
guess, is the voids between clumps since clumps are smaller than the gts
surface.
