I need your kind help. I am trying to make a finite element model for the deformation of the disc, ligaments around the spine (L3L4L5 vertebral segment). What are the applied forces to the top of L3 that we should consider for our model? And how to calculate these forces? should I just use the "joint reaction forces" at the joint or should I calculate some other moment or other reaction here?
For the reaction forces on the top of L3 vertebra, which muscles are being calculated? Can I know how much each muscle contributes the joint reaction forces on top of L3? Are there any muscles or body weight or any other forces also?
I think what you are looking for is the AnyForceMomentMeasure and the AnyForceMomentMeasure2 classes. with them you can identify which forces are working on a given reference frame.
There are links to class examples of how to use them in the AnyScript reference manual.
From the anybody software click "Help" and then "AnyScript Reference" there you can search for the class name.
A bonus tip is that if you place your cursor on a class name in the editor window - you can press "F1" to jump directly to the class reference page in the manual.
