Triaxial test using polyhedral particles
Hello,
I am new user of YADE and I’m trying to do a Triaxial test using polyhedral shapes.
To prepare the sample I created a cloud of spheres and then replace them with polyhedral particles.
Therefore, my question is:
1- Is it possible to use polyhedral shapes using periodic boundary conditions?
If you have any suggestions about using polyhedral particles please tell me! (the following is my code)
sp0=pack.
NbParticles=
#### to replace the spheres with polyhedral particles ####
for center,radius in sp0:
t=polyhedra_
t.state.pos=center ### to give the polyhedral particle the same position as the sphere
O.bodies.append(t)
2- I am also trying to prepare a Triaxial test with polyhedral particles and walls:
I created walls using aabbWalls
Use the TriaxialStressC
However, when I run the simulation I get a warning saying that the verletDist is set to 0 because no spheres are found… and the walls move with no contacts with the particles. I used the following engine and laws:
O.engines=[
ForceResetter(),
InsertionSortC
InteractionLoop(
[Ig2_
[Ip2_
[Law2_
),
O.dt=0.
...... I tried to change the time step but its the same.
When I run a previous example “examples_
Thank you for your help!
