jessica sjah is still having a problem:
Hi,
Thank you for all of your information... I've also seen post #174453
:)...
I have another question.
How could I apply different gravity to the spheres in one generated box?
I want to make a sample for modelling hole erosion test, so I want to make a
sample made of spheres with a hole in the middle of the sample...
In my mind, I can make it by applying different sign for gravity along
direction z (based on their position or id) when I generate the spheres and
then stabilize them. Have anyone any idea to realize it in O.engines?
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]),
InteractionLoop(
# handle sphere+sphere and facet+sphere collisions
[Ig2_Sphere_Sphere_L3Geom(),Ig2_Facet_Sphere_L3Geom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_L3Geom_FrictPhys_ElPerfPl()]
),
GravityEngine(gravity=(0,0,-9.81)),
NewtonIntegrator(damping=0.4),
]
Thank you very much for your answers :)... have a good day.
