Question #691560 on Yade changed:
https://answers.launchpad.net/yade/+question/691560

    Status: Needs information => Open

jsonscript gave more information on the question:
Hello.
   some codes are listed here:
O.engines=[
	ForceResetter(),
	InsertionSortCollider([Bo1_Sphere_Aabb()]),
	InteractionLoop(
		[Ig2_Sphere_Sphere_ScGeom()],
		[Ip2_FrictMat_FrictMat_MindlinPhys()],
		[Law2_ScGeom_MindlinPhys_Mindlin(includeMoment=False)]
	),

	GlobalStiffnessTimeStepper(timeStepUpdateInterval=100,label='ts',targetDt=1e-2),
	# PeriTriaxController(dynCell=True,maxUnbalanced=2e-3,relStressTol=2e-4,goal=[-1e5,-1e5,-1e5],stressMask=7,globUpdate=5,maxStrainRate=[1,1,1],doneHook='triaxDone()',label='triax'),
	NewtonIntegrator(damping=.2,label="newton"),
	PyRunner(iterPeriod=100,command='defData()'),
]

         After consolidation,   I meaurse the contact normal by i.geom.normal in O.interactions..then draw the rose diagram..
        The rose diagram is listed here:
