Meaning of Ox, Oy and Oz getting Bodykinematics results

[francisco rus]

I would like to know what it is the meaning of the results which are follow by "0x, 0y and 0z" when using the tool Analyze and you want the bodykinematics outputs. I know for what I have read that it is something about the orientation of the solids, but is it the orientation of the local coordinates of a solid from the global? The opposite? May be the Euler's angles? I don't have it clear. Thank you.

Sorry that finding this info isn't intuitive. The .sto output files actually have headers at the top of each file. You can open .sto's in either a text editor (e.g., Notepad, Notepad++) or Excel. The top of the file has info such as this:

Body segment orientations are described using body-fixed X-Y-Z Euler angles.

Angular velocities and accelerations are given about the body-local axes.

Hello,

The leading "O" signifies the Orientation/Angular velocities/...

You can also check the source code on github for the implementation of BodyKinematics if you're interested. Please let us know if you need help locating it.
