Hi Laura

I mean something like this:

#########################################
O.load('/path/spheresurface.yade')

MatBal=O.materials.append(FrictMat(...))


### green sphere
greenSphere = sphere((0.108,0.2289647116,0.7175),0.0199647116,color=(0,1,0),material='mat1')
# no need of utils.sphere
greenSphereId = O.bodies.append(greenSphere)



def guardar():
        ...

O.engines=[
        ForceResetter(),
        InsertionSortCollider(
                [Bo1_Sphere_Aabb(),
                        Bo1_Facet_Aabb(),
                        Bo1_Box_Aabb(),
                        Bo1_Wall_Aabb()]),
        InteractionLoop(
                [Ig2_Sphere_Sphere_ScGeom(),
                        Ig2_Facet_Sphere_ScGeom(),
                        Ig2_Wall_Sphere_ScGeom(),
                        Ig2_Box_Sphere_ScGeom()],
                [Ip2_FrictMat_FrictMat_FrictPhys()],
                [Law2_ScGeom_FrictPhys_CundallStrack()]
        ),
        # PyRunner(command='force()',
        #        iterPeriod=1,initRun=True,label='checker'), # this
PyRunner will not be used
        PyRunner(command='guardar()',
                iterPeriod=1,initRun=True,label='checker'),
        NewtonIntegrator(damping=0.5,gravity=(0,-9.81,0),label='newton'),
        yade.qt.SnapshotEngine(fileBase='3d-',iterPeriod=
1000,label='snapshot')
]
O.dt=utils.PWaveTimeStep()

greenSphere.state.vel = (1,0,0) # this :-)
