Yufan Zhao gave more information on the question:
Part of script about material defining and engine is shown as below:
#############
idRake=O.materials.append(FrictMat(young=193e9,poisson=0.25,density=7990,frictionAngle=0.8,label="stainless"))
idPowder+O.materials.append(FrictMat(young=220e9,poisson=0.3,density=8287,frictionAngle=0.506,label="powder"))
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_MindlinPhys()],
[Law2_ScGeom_MindlinPhys_Mindlin()],
NewtonIntegrator(gravity=(0,0,-9.81),damping=0.0,label='newton'),
TranslationEngine(.................),]
##############
I would like to make the simulation more realistic and if viscous
damping is considered, what additional parameters of materials and
system should I input?
Thanks very much for your help!
