Hi, 
I am trying to simulate a pull out of a geogrid. AT the beginning I want to deposit the grains and the geogrid in a box (layer of grains, grid, another layer of grains on the top) . The problem is that the geogrid is not blocked by the grains in the middle, seems that the interaction is not taken into account. The grid interpenetrate the deposited grains and goes out of the box.

This is  my O.engines :
O.engines=[
	ForceResetter(),
	InsertionSortCollider([Bo1_Sphere_Aabb(aabbEnlargeFactor=1.2,label='aabb'),
		Bo1_GridConnection_Aabb(),Bo1_Box_Aabb()]),
	InteractionLoop(
		[Ig2_Sphere_Sphere_ScGeom6D(interactionDetectionFactor=1.2),Ig2_GridNode_GridNode_GridNodeGeom6D(),Ig2_Box_Sphere_ScGeom(),Ig2_Sphere_GridConnection_ScGridCoGeom()],
		[Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(setCohesionNow=True,setCohesionOnNewContacts=False),Ip2_FrictMat_FrictMat_FrictPhys()],
		[Law2_ScGeom6D_CohFrictPhys_CohesionMoment(),Law2_ScGeom_FrictPhys_CundallStrack()]
	),
        GlobalStiffnessTimeStepper(timestepSafetyCoefficient=0.6),
	NewtonIntegrator(gravity=(0,0,-0.1),damping=0.9,label='newton')
]
