Notice that the accelerations are between approximately -500 and 600.
Now, let us introduce some random noise. An easy way to do so is to simply truncate the decimals off the
columns in the marker trajectory file. Please download this file, where the numbers only have three
decimals: P2trunc.txt
. Then make the following change in the model:
AnyKinEqInterPolDriver M1Driver = {
Type = Bspline;
BsplineOrder = 4;
FileName = "P2trunc.txt";
AnyKinMeasure &Lin = .M1Lin;
// MeasureOrganizer = {0};
Reaction.Type = {On, On, On};
};
Please reload (F7) the model and re-run (F5) the kinematic analysis. The pendulum appears to move as it
did before. If we investigate the positions of the driven point, then we get the following:
