I'm not a very experienced Yade user and I'm trying to construct a simulation
of an oedometric test. I'm using the cohesive frictional law in order to model
cohesion between the particles in the simulation. The limiting walls have been
constructed using the facetBox tool:
O.bodies.append(geom.facetBox(box_dimensions/2,box_dimensions/2,wallMask=31))
and the moving plate by the wall tool:
top_label =
O.bodies.append(facet([np.array([0,0,voxelSize*scale*grains.shape[0]]),
np.array([voxelSize*scale*grains.shape[2]/2,0,voxelSize*scale*grains.shape[0]]),
np.array([0,voxelSize*scale*grains.shape[1]/2,voxelSize*scale*grains.shape[0]])],wire=False))
as suggested by the oedometric
example(https://yade-dem.org/doc/tutorial-examples.html). My code is rather
long and since I believe it's not relevant for my question, I'm only pasting
the crutial parts.
My question is - since I'm using the the Law2_ScGeom6D_CohFrictPhys interaction
law:
myIgeoms = [yade.Ig2_Sphere_Sphere_ScGeom6D(),yade.Ig2_Facet_Sphere_ScGeom6D()]
myIphyss = [yade.Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(setCohesionNow=True)]
myLaw2s =
[yade.Law2_ScGeom6D_CohFrictPhys_CohesionMoment(useIncrementalForm=True,
always_use_moment_law=False)]
which geometry law should I use for the interaction between the wall and the
spheres? Moreover - is the wall an appropriate choice for constructing the
moving plate? Would a facet be a better choice?
Any help will be greatly appreciated.
