I provide more information on this topic, maybe its really just a script
syntax problem ...
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb(),Bo1_Box_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Box_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_MindlinCapillaryPhys(betan=0.9,betas=0.9,label='ContactModel')],
[Law2_ScGeom_MindlinPhys_Mindlin(neverErase=False,label='Mindlin')]
),
Law2_ScGeom_CapillaryPhys_Capillarity(CapillaryPressure=suction,fusionDetection=True,label='CapPhys'),
GlobalStiffnessTimeStepper(active=1,timeStepUpdateInterval=1,timestepSafetyCoefficient=0.8,
defaultDt=0.9*utils.PWaveTimeStep(),label='TimeStepper'),
NewtonIntegrator(gravity=(0,0,-9.81),damping=local_damping_pre,label='integrator')
]
#Now I want to deactivate GlobalStiffnessTimeStepper (activate later)
TimeStepper.dead=True
#Set preferred time step:
O.dt=1e-8
When I look at time step in yade GUI, time stepper is still active and it has
time step > 1e-8 !
Did I do something wrong? The script was working well with an older version of
yade (before density scaling was introduced). Now it makes calculation instable
(explosion), because time step is too high.

Title:
new GlobalStiffnessTimeStepper can not be deactivated anymore in
O.engines
Status in Yet Another Dynamic Engine:
Invalid
Bug description:
I tried to deactivate GlobalStiffnessTimeStepper in O.engines with
GlobalStiffnessTimeStepper.dead=True
or with
GlobalStiffnessTimeStepper.active=False
, but this commands will not deactivate it.
To solve the problem one just have not to declare it in O.engines.
