I tried F 11 but it doesn't view any. I think that command suppose to view the  simulation
below is the  script

# basic simulation showing sphere falling ball gravity,
# bouncing against another sphere representing the support

# DATA COMPONENTS

# add 2 particles to the simulation
# they the default material (utils.defaultMat)
O.bodies.append([
   # fixed: particle's position in space will not change (support)
   sphere(center=(0,0,0),radius=.5,fixed=True),
   # this particles is free, subject to dynamics
   sphere((0,0,2),.5)
])

# FUNCTIONAL COMPONENTS

# simulation loop -- see presentation for the explanation
O.engines=[
   ForceResetter(),
   InsertionSortCollider([Bo1_Sphere_Aabb()]),
   InteractionLoop(
      [Ig2_Sphere_Sphere_L3Geom()],        # collision geometry 
      [Ip2_FrictMat_FrictMat_FrictPhys()], # collision "physics"
      [Law2_L3Geom_FrictPhys_ElPerfPl()]   # contact law -- apply forces
   ),
   # Apply gravity force to particles. damping: numerical dissipation of energy.
   NewtonIntegrator(gravity=(0,0,-9.81),damping=0.1)
]

# set timestep to a fraction of the critical timestep
# the fraction is very small, so that the simulation is not too fast
# and the motion can be observed
O.dt=.5e-4*PWaveTimeStep()

# save the simulation, so that it can be reloaded later, for
experimentation

O.saveTmp()
