Hi, everyone
I am interested to create the ligament in the OpenSim and one of the parameters of the ligament is the Resting length of the ligament.
What is the definition of the resting length of the ligament? Is that the zero-load length of ligament or the reference length of ligament ?
Thanks for any help.

It is the length at which the ligament has zero strain.
The normalized strain = (path.length - rest_length)/rest_length;
The ligament force = force_length_curve(strain) * pcsa_force.

Thanks for your help
