In my experience, Polyhedra simulations (CGAL library more than YADE version ?) was working several years ago (first half of 2020) indeed better than nowadays -- 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

I am using yade 2020.01a version, not sure about cgal. Also, part of those that I was able to import resulted in complete mess, nothing as it should be. I used same code with some earlier version of yade and it was flawless, so I will try with some oleder versions.

Question #705031 on Yade changed: https://answers.launchpad.net/yade/+question/705031 Jérôme Duriez posted a new comment: Hi, In my experience (CGAL version 4.11 to 5.02), using Polyhedra is currently at a significant risk of segmentation faults, see https://gitlab.com/yade-dev/trunk/-/issues/242 and links therein. You can tell us your YADE / CGAL version to try to see if your own issue can be related. (You can also check RAM usage during your simulation to see how much this is a matter of data volume. Even though I'm not sure it would lead to a "Segmentation fault" in this case ?) -- 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
[Yade-users] [Question #705031]: Poly import core dumped
New question #705031 on Yade:
https://answers.launchpad.net/yade/+question/705031
Hi there,
I am trying to import large number of polyhedra in my model by importing
vertices of each poly.
Following script works until ~17k of polys is imported, then I receive
Segmentation fault. Any thoughts?
Here is link for poly file, where vertex coordinates are written in each line;
last point of each file line is polys centroid:
https://drive.google.com/file/d/13lm7qvKHbHxteFKUB5tZejohU7jAjgCj/view?usp=share_link
model script:
from yade import polyhedra_utils
import ast
m = PolyhedraMat()
m.density = 2700
m.Ks = 10E8
m.Kn = 10E8
m.frictionAngle = radians(30)
file = open("Fragments")
for line in file:
vertex=[]
vertex.append(ast.literal_eval(line))
t = polyhedra_utils.polyhedra(material=m, size=0, seed=0, color=
polyhedra_utils.randomColor(), v=vertex[0][0:(len(vertex)-3)])
t.state.pos=vertex[0][len(vertex)-2]
O.bodies.append(t)
del vertex[:]
Thanks
Veljko
