Question regarding Static Optimization Constraint

Hi all,
I am doing a Static Optimization and the model seems to be working well visually, but I am getting constraint violation. The values are very small, so I am not sure about how much impact this has.
This is an example of the output at one time instant
time = 8.55723 Performance = 3.32146 Constraint violation = 4.67229e-12
The value of the violation is basically zero. Does this mean that the model works well for my example?
Additionally, how can I verify the output of the simulation?
I am getting forces and muscles activation, but what is the best to verify the value of the outputs ?

All your help is much appreciated,

Hi, your constraint violation value is fine (low enough). Please see these posts as well:

For evaluating your simulation, there is a great paper by Hicks et al. (2015), and also, this page:
