My aim is to calculate joint forces in the Demo.SliderCrank3D.any file.
But I´m confused about my results. Now I´m not sure if I understand
the driver well.
-The driver owns a constant acceleraton (Reference Manual), but how
big is this and how long is the rotation time, just 1 second? Where
and how can I define acceleration and time?
-What is really the meaning of DriverVel = {6.28} ? Just the velocity
at t=0 (Reference Manual)?
Please see the answers next to your questions below:

The default value of the acceleration is zero, so unless you specify
DriverAcc = {something};
you will get a driver moving at constant speed. If, for instance,
you specify
DriverAcc = {pi};
then at t = 0.3 second the speed will be 2pi + 0.3pi = 2.3*pi.
The time is controlled in the study at the bottom of th example
file. The study has a tStart and a tEnd (defauting to 0 and 1 second
respectively). If ou want the simulation to run further, simple
specify, for instance
tEnd = 2.0;
in the study.
> -What is really the meaning of DriverVel = {6.28} ? Just the
velocity at t=0 (Reference Manual)?
This means that the driver velocity is 6.28 (= 2*pi) at time t = 0.
If there is no acceleration specified, then this is a constant speed
that applies for all times.
