Klaus Thoeni proposed the following answer:
Hi,
applying forces to facets which are non-dynamic forces has no effect as
Jan already mentioned.
Have a look at this:
# -*- coding: utf-8 -*-
from yade import qt
## PhysicalParameters
Young = 30e9
Poisson = 0.2
Density=1000
# Append a material
mat=O.materials.append(FrictMat(young=Young,poisson=Poisson,density=Density,frictionAngle=.5))
facets=O.bodies.append(utils.geom.facetBox((.5,.5,.5),(.5,.5,.5),wallMask=63,material=mat))
sphere=O.bodies.append([sphere([0.5,0.5,0.5],.2,material=mat)])
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]),
InteractionLoop(
# handle sphere+sphere and facet+sphere collisions
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack()]
),
HarmonicMotionEngine(A=[0.4,0,0], f=[5.,0,0.0], fi = [pi/2.,0.0,0.0],
ids = facets),
ForceEngine(force=(0,0,-10.),ids=sphere),
GlobalStiffnessTimeStepper(timestepSafetyCoefficient=0.01),
NewtonIntegrator(damping=0.4,gravity=(0,0,-9.81)),
]
O.saveTmp()
## to see it
qt.View()
#O.run()
HTH
