[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

Re: [Yade-users] [Question #294932]: passing grains
Question #294932 on Yade changed:
https://answers.launchpad.net/yade/+question/294932
Status: Open => Answered
velimier proposed the following answer:
1st: you should increase the young values and that will solve the problem with
passing grains.
2nd: you may import the ground as surface and present it as facets. It is
something like this:
surf=gts.read(open('yourSurf.gts'))
O.bodies.append(pack.gtsSurface2Facets(surf,wire=True)) [see gts-horse example]
if you are using CAD to draw the ground you can export that surface to
the .gts format directly (depends on software, Rhinoceros has that
option), or you can export the surface to .stl format and convert it to
.gts using stl2gts tool.
Hope it helps,
Veljko

[Yade-users] [Question #291529]: Polyhedra longest edge to vtk
New question #291529 on Yade: https://answers.launchpad.net/yade/+question/291529 Hi, I am creating simulation by importing voronoi cells to yade as polyhedra. Along with the computation of the voronoi cells I can determine the longest edge of each cell/polhedra. My goal is to export the polhedrons as .vtk and to be able to postprocess them using their longest edge as parameter. Questions are: 1. How to prescribe the longest edge to each polyhedron prior the creation of polyhedrons as "custom" parameter and use it during the simulation? 2. How to export the longest edge of each polyhedron to .vtk to be able to postprocess it in paraview? -- 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 #263072]: Manipulating blocks created using jointedCohesiveFrictionalPM
New question #263072 on Yade: https://answers.launchpad.net/yade/+question/263072 Hi, I want to create model that represent highly jointed rock mass using jointedCohesiveFrictionalPM. At first I want to create rock block and then to add joints into that block. Since I have dense fracture network that I want to add I need to use spheres with small radii in order to be able to create even smallest subblocks that are created by joint intersections. But before i proceed to simulation I would like to rationalize whole model and to reduce overall number of spheres but to keep all subblocks. And here comes my question: Is it possible to determine what spheres belong to each subblock? Or to transform subblocks into clumps and then replace spheres with small radii with ones with larger radii? I'd appreciate any suggestions.
