Hi François,

To modify the value of damping during a simulation, you should, first,
identify NewtonIntegrator:

newton=utils.typedEngine('NewtonIntegrator')

then, you can access the damping value like this:

newton.damping

To modify it, you can do:

newton.damping=yourValue

Concerning the substraction (deletion?) of an engine, you can try to type
this:

O.engines=O.engines[:2]+O.engines[3:0]

It should remove the 3rd engine (for example). So you have to identify the
position of your engine in the initial list. Not sure it is the propest
solution though...

Cheers

  Luc
