I used this flag already and it changed nothing on the effect that the velocity
got ignored. The mass is also set to 1.0 to avoid start errors. So concerning
the values things should be alright yet only the forces added before the
simulation step is used but not the velocity. I can set velocity always to 0 and
apply the velocity as force but I suspect this to mess up the simulation.
