Force vectors not displayed

[Félix Lefebvre]

Contrariwise to OpenSim 3.3, in OpenSim 4.0 force vectors are not displayed after Inverse Dynamics.

How is it possible to display them ?
If impossible, is it due to Kistler force plate data ? (Inverse Dynamics results looks right in the .sto file)

Thanks,

Felix

Hi Felix,

The OpenSim 4.0 application is more strict in the type of data it displays from .sto files. In previous versions you could have a mix of state values, forces and marker trajectories in one sto file. This is not supported anymore, instead you need to "associate" the motion data for Forces or Marker trajectories to the motion in order for the force vectors and/or markers to be displayed. Details in the link below

This behavior is unrelated to what force plate type you're using and also is unrelated to the tools/computation performed by the tools.

Hope this helps,

I am expecting v_local to be actually equivalent to the initial 3 segments of vel cluster. I simply acknowledged v_local is an element of second and third introductions which does not mae sense to me. why pelvis turn esteem can influence pelvis list precise speed? I dont's think this is a Gimbal bolt as even pelvis_list=5 degrees can cause mistaken outcomes. (see joined jpeg )

For muscle moment arm calculations, we always work with one muscle at a time. To avoid unnecessarily complicated notation, it is to be understood here that the symbols refer to the subset of the multibody model (bodies and mobilities) that affects the muscle of interest expository essay guide.
