Hi,
I tried to make an Induced Accelerations Analysis but I always get the same mistake in OpenSim:
Loading states from file E:\Biomedical Engineering\masterarbeit\Selbst gemacht\torsionalanklespring\Ohne\walk_subject01_knee_spring_knee_spring_states.sto.

Performing Induced Accelerations Analysis
time = 0.03
Exception:
ArrayPtrs.get: Array index out of bounds.
Could someone help me to avoid this mistake?
And I have another questions concerning the ConstraintSet for the IAA. If I have external forces, is it then necessary to apply a constraint or can I just ignore it?
Thanks very much for your help!
