Status: Needs information => Answered
Jan Stránský proposed the following answer:
###
O.materials.append(CohFrictMat(
isCohesive=True,
normalCohesion=1e99,
shearCohesion=1e99,
))
O.engines = [
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom6D()],
[Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(
setCohesionNow=True,
setCohesionOnNewContacts=False,
)],
[Law2_ScGeom6D_CohFrictPhys_CohesionMoment()]
),
NewtonIntegrator(),
]
spheres = s1,s2,s3 = (
sphere((0,0,0),1),
sphere((1,0,0),1),
sphere((0,1,0),1),
)
O.bodies.append(spheres)
O.dt = 0
O.step()
for i in O.interactions:
i.phys.unp = i.geom.penetrationDepth
O.dt = 1e-7
#s1.state.vel = (-200,0,0)
###
Cheers
Jan
