Hi all,
I have set the material parameters through the following scripts.
SoilMat=O.materials.append(CohFrictMat(young=E0,poisson=Pois,density=2350,frictionAngle=Fric,normalCohesion=coh,shearCohesion=Pois*coh,isCohesive=True,momentRotationLaw=True,etaRoll=0.1,label='soil'))
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(aabbEnlargeFactor=intRadius,label='is2aabb'),Bo1_Box_Aabb()],verletDist=.05*sphereRadius),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom6D(interactionDetectionFactor=intRadius,label='ss2sc'),Ig2_Box_Sphere_ScGeom6D()],
[Ip2_FrictMat_FrictMat_FrictPhys(),
Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(label='cohesiveIp')],
[Law2_ScGeom_FrictPhys_CundallStrack(),Law2_ScGeom6D_CohFrictPhys_CohesionMoment(
useIncrementalForm=True,
always_use_moment_law=True,
label='cohesiveLaw')]
),
NewtonIntegrator(damping=0.4, label='Newton'),
]
However when I check the normalAdhesion between the interactions throngh the
follow function, the value of coho is zero.
def change_para():
for i in O.interactions:
coh0=i.phys.normalAdhesion
print "cohension:",coh0
change_para()
Which indicated that there is no relationship between Material parameters and
Interaction parameters. It is true?
For one simulation, am i only set the material parameters or Interaction
parameters?
And if I want to set the particle's parameters throught Interaction (
Ip2_CohFrictMat_CohFrictMat_CohFrictPhys), how can I define the same simulation
parameters as that throught Mateials parameters, for example:
SoilMat=O.materials.append(CohFrictMat(young=E0,poisson=Pois,density=2350,frictionAngle=Fric,normalCohesion=coh,shearCohesion=Pois*coh,isCohesive=True,momentRotationLaw=True,etaRoll=0.1,label='soil'))
Thanks a lot!
Henry
