Hi Luis,

what about this script (slightly modified your original version)?

###################################
#!/usr/bin/python
# -*- coding: utf-8 -*-

# Spheres
O.materials.append(CohFrictMat(young=15e8,poisson=0.3,density=1000,frictionAngle=radians(30),label='spheres'))
O.bodies.append([
utils.sphere(center=(0.5,0.5,0.5),radius=0.1,material='spheres',fixed=False),
utils.sphere(center=(0.5,0.2,0.2),radius=0.1,material='spheres',fixed=False),
utils.sphere(center=(0.5,-0.5,0.5),radius=0.3,material='spheres',fixed=True),
utils.sphere(center=(0.5,1.5,0.5),radius=0.3,material='spheres',fixed=True)
])

########################################################################################
cid,ids = O.bodies.appendClumped(aabbWalls(((0,0,0),(1,1,1)),.02,1))
box = O.bodies[cid]
box.state.vel = (0,10,0)

O.engines=[
  ForceResetter(),
  InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Box_Aabb()]),
  InteractionLoop(

    [Ip2_FrictMat_FrictMat_FrictPhys()],
    [Law2_ScGeom_FrictPhys_CundallStrack()]
  ),

  NewtonIntegrator(damping=0.1,gravity=[0,0,-9.81]),

]
O.dt=1e-3*utils.PWaveTimeStep()
