Static optimization failed

[SOUVIK PAUL]

Hello everyone its Paul from IIT Delhi, India. I'm currently into developing a Full body musculoskeletal model with 284 millard muscles. Whlie performing static optimization I'm facing some issues. I'ts saying----" SimTK Exception thrown at InteriorPointOptimizer.cpp:264:
Optimizer failed: Ipopt: Maximum iterations exceeded (status -1)
OPTIMIZATION FAILED...
StaticOptimization.record: The optimizer could not find a solution at time = 1.68.
The model appears unsuitable for static optimization.
Try appending the model with additional force(s) or locking joint(s) to reduce the following acceleration constraint violation(s):

Where as I have tried also attaching reserve actuator to my model.
Can anyone please suggest some futher steps to rectify this errors.
Any help will be appreciated. Thank You
