pull out joint velocity and acceleration values as variables

[Walter]

I know how to pull out a joint displacement value as a variable (nodedisp). But how do I pull out joint velocity and acceleration values as varibles. Thank you for your answers.

Sincerely,

Walter

I have a similar question. Are there other commands, similar to “nodedisp” or “getTime” commands, but returning other responses? Other responses could be, for example:
- The stress or the strain of a specific fiber section
- The velocity or acceleration of a specific joint
- Others
I would appreciate any suggestion.
Thank you.
