veerawat is still having a problem:
I want to make a model bearing capacity of soil . But I can’t resize
the pressure wall. I want to resize the pressed wall, what to do?
This is my code#######
from yade import pack
sp=pack.SpherePack()
## corners of the initial packing
mn,mx=Vector3(0,0,0),Vector3(10,10,10)
## box size, radius, number of ball
sp.makeCloud(minCorner=mn,maxCorner=mx,rRelFuzz=.1,num=1500)
## create material #0, which will be used as default
O.materials.append(FrictMat(young=15000000,poisson=.4,frictionAngle=radians(30),density=2600,label='spheres'))
O.materials.append(FrictMat(young=15000000,poisson=.4,frictionAngle=0,density=0,label='frictionless'))
## copy spheres from the packing into the scene
## use default material, don't care about that for now
O.bodies.append([sphere(center,rad,material='spheres') for center,rad in sp])
## create walls around the packing
walls=aabbWalls(thickness=1e-10,material='frictionless')
wallIds=O.bodies.append(walls)
# wall of each side
triax=TriaxialCompressionEngine(
wall_bottom_id=wallIds[2],
wall_top_id=wallIds[2],
wall_left_id=wallIds[0],
wall_right_id=wallIds[2],
wall_back_id=wallIds[2],
wall_front_id=wallIds[2],
internalCompaction=False,
sigmaIsoCompaction=-50000,
sigmaLateralConfinement=-50000,
max_vel=10,
strainRate=0.01,
label="triax"
)
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Box_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Box_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack()]
),
GlobalStiffnessTimeStepper(active=1,timeStepUpdateInterval=100,timestepSafetyCoefficient=0.8),
triax,
NewtonIntegrator(damping=.4)
]
from yade import plot
O.engines=O.engines[0:5]+[PyRunner(iterPeriod=20,command='history()',label='recorder')]+O.engines[5:7]
def history():
plot.addData(e11=-triax.strain[0], e22=-triax.strain[1],
e33=-triax.strain[2],
s11=-triax.stress(0)[0],
s22=-triax.stress(2)[1],
s33=-triax.stress(4)[2],
i=O.iter)
plot.plots={'i': ('e11','e22','e33',None,'s11','s22','s33')}
O.saveTmp()
plot.plot()
