hi,
I wanna generate a 'wall' object to act as infinite axes-aligned plane, there
is a example 'wall.py' in example file which runs as what i thought, somehow it
wont work as it should be when i add it to my code...wall acted as air and
sphere just went through it. please help me with this problem. below is two
scripts 'wall.py' the example and my script 'air-wall.py'.
#--------------------------------------------wall.py---------------------------------------
O.materials.append(FrictMat(young=30e9,density=1000,poisson=.2,frictionAngle=.5))
O.bodies.append([
wall(1,axis=2,sense=-1),
wall(-5,axis=0,sense=1),
wall(1,axis=1),
wall((1,0,0),0),
sphere([0,0,0],.5),
sphere([-4,-4,-3],.5)
])
Gl1_Wall(div=10)
from yade import qt
qt.Controller()
qt.View()
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb(),Bo1_Wall_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Wall_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack()],
),
NewtonIntegrator(damping=0.01,gravity=[1e2,1e2,1e2]),
]
O.dt=PWaveTimeStep()
O.save('/tmp/a.xml')
O.saveTmp()
#---------------------------------------------------------------------------------------------------------
#------------------------------------------------------air-wall.py-------------------------------------
#sphere
O.materials.append(FrictMat(young=4.0e6,poisson=.3,frictionAngle=30,density=2630e+6,label='sphereMat'))#for
sphere
s=utils.sphere(center=[0,100e-3,100e-3],radius=20e-3)
O.bodies.append(s)
#### Wall ####
O.materials.append(FrictMat(young=1.0e6,poisson=0.2,density=2.60e3,frictionAngle=20,label='wallmat'))
O.bodies.append(utils.wall(0,axis=2))
from yade import qt
qt.Controller()
qt.View()
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb(),Bo1_Wall_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Wall_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],

),
NewtonIntegrator(damping=0.01,gravity=[0,0,-1e2]),
