Kinematics Error - indefinite velocities

kinematics

#1

Hi,

I got this error and I cannot figure out where is the problem:

InverseDynamicStudy.InitialConditions : Kinematic analysis failed in time step 0 : Indefinite velocities

MarkerTracking is running but when I want to start the InverseDynamics / Kinematics Analysis, this error appears.
I am using a human model and I attached a tool at the hand node. I am saving position results of the movement of my tool (MarkerTracking) and load them via “JointsAndDriversOptimized.any”
Can anyone help me with this issue?

Thanks!

Hi @WGND.

Your approach seem correct. So I can’t readily tell what the problem is. Indefinite velocities is not an error I have stumbled on recently, so I can’t guess what is causing it.

Maybe you could share the model, so we could take a closer look. (But don’t upload it publically here)

Best wishes,
Morten
