>Yeah but no incrementation is done, isn't it ?

In your original script nothing change, you are right :-) you set

fEngine.force[1] = -forcetest     # forcestest=0 initially

__before__ the simulation, and because forcestest=0, it is indeed no
change. After the simulation starts, the only thing is printing O.iter
and 10*O.iter (=forcetest) into stdout every 1s.

If you want to change force (let's say) each 100 iteration, add

PyRunner(command="fEngine.force[1]=someNewValue", iterPeriod=100),

line into your O.engines.
