Hi stephen,
Welcome to yade community.
In yade you have to define materials (e.g. one material for particles
and one for boundaries):
### properties:
density = 2650
shear_modulus = 2e5
poisson_ratio = 0.15
young_modulus = 2*shear_modulus*(1+poisson_ratio)
### define materials:
SphereMat =
FrictMat(young=young_modulus,poisson=poisson_ratio,density=density,frictionAngle=0.5)
BoundaryMat =
FrictMat(young=young_modulus,poisson=poisson_ratio,frictionAngle=1)
O.materials.append(SphereMat)
O.materials.append(BoundaryMat)
Then you can use the materials in the generation process:
O.bodies.append(sphere([0,0,0],radius=R, material = SphereMat, fixed=True))
O.bodies.append(geom.facetBox((0.035,0.035,0.035),(0.035,0.035,0.035),wallMask=15,
material = BoundaryMat, dynamic=1))
Hope it helps,
Christian
