In addition to SmoothSphereHalfSpaceForce, can other types of contact forces be tracked in Moco ? For example, in the process of going up and down the stairs, it is obviously inappropriate to use SmoothSphereHalfSpaceForce.

The opensim model of 3RPS parallel mechanism

Hi Nick, Thank you very much for your answer, but at the same time, I would like to ask you another question. In MOCO optimization, I often achieve ideal results within 100 iterations. However, MOCO will continue to optimize and iterate, and may not find the optimal solution until the 500th iteratio...

Hello everyone, what is the meaning of each parameter in each iteration when using Moco for optimization? As shown in the figure, and how to evaluate the results of each optimization iteration based on them?

The theoretical description of ligament modeling in this article is very confusing and difficult to understand.

In fact I urgently want to know, how the mathematical model of the non-linear ligament inside is built, what its functional relation is like, what is represented by each parameter inside, can I do not know how to get that material, I have reviewed a lot of literature, and can each model the ligament...

You should install the plugin you need for this non-linear ligament. The following items can be viewed:https://simtk.org/projects/nlsrv1

Thank you very much. This is exactly what I need
