Aoxi Zhang is still having a problem:
Hi,
I'd like also use labels for engines.
But sometimes I found that using label cannot successfully control the engine. For instance, in phase2.py:
O.engines[3].dead=True## turn of GlobalStiffnessTimeStepper
# TimeStepper.dead=True## Note, use label cannot successfully close time stepper
In above codes, I want to close GlobalStiffnessTimeStepper, if I use
TimeStepper.dead=True, it doesn't work. Thereby, I use
O.engines[3].dead=True to turn of GlobalStiffnessTimeStepper. I don't
know why.
Regarding the original question, I use newton.damping=0.9 and/or
NewtonIntegrator.damping=0.9 to set the damping. The problem is still
there :(
Any ideas or comments are welcome.
Best,
Aoxi
