Tnx peter i will do that and report the result here.

but i also have another question: to define a contact between ligament and the vertebral body, it is better to define a joint, and For the reference side I have to select the whole surface of vertevral body, and this requires more calculations. And I tried to create a point on the surface of the vertebra to establish a connection between a point on the ligament and a point on the surface of the vertebra. But I could not create a point in the desired place that is visible in the mechanical. Do you have any suggestions to fix this issue?
