Robert Caulk proposed the following answer:
Hello,
If you want to redefine gravity, you need to use the gravity member of
the newtonintegrator object:
a=(0,0,0)
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]),
InteractionLoop(
# handle sphere+sphere and facet+sphere collisions
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack()]
),
NewtonIntegrator(gravity=a,damping=0.4, label='newtonInt'),
PyRunner(command='gravity()',iterPeriod=1)
]
def graviy():
newtonInt.gravity = (0,0,1)
