Hi,
I have a quick question. When I enter a ligament definition with #BM_TRUNK_LUMBAR_LIGAMENTS ON into the lumbar spine model, does Joint Reaction Force (for example, L4L5ProximoDistalForce) automatically take into account the ligament contribution as well?
Yes, when you add mechanical elements that are part of you study - they will automatically be picked up by the InverseDynamics simulation and have an effect.
