Error while opening the model

Post by Nikita Kuznetsov » Wed Mar 29, 2023 7:38 am

Hi!

Thank you for this model! I just tried opening it in OpenSim 4.4. and got this error:

Object type NonLinearLigament not recognized
Object::newInstanceOfType(): object type 'NonLinearLigament' is not a registered Object!

The model then did not load at all. I then tried opening it in OpenSim 3.2, and it worked, but the error is still there. Could you explain what is the "nonlinearLigament" object here? Also, I'm I correct that this model can only work properly in 3.3? Or can I work with it in 4.4?

Thanks,
Nikita

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

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 differently.
