Hello ,
Could you please let me know to resolve this issue after running the CMC on the new version 4.5. However, the same data use on 4.4 version of OpenSim never crashed or failed. Here using the new OpenSim version 4.5 failed as shown below. Please advise. Thank you
CMC::compute Controls, t = 4.06
CMC::compute Controls, t = 4.07
SimTK Exception thrown at InteriorPointOptimizer.cpp:265:
Optimizer failed: Ipopt: Restoration failed (status -2)
OPTIMIZATION FAILED...
CMC::computeControls: Optimizer could not find a solution.
Unable to find a feasible solution at time = 4.07.
Model cannot generate the forces necessary to achieve the target acceleration.
Possible issues: 1. not all model degrees-of-freedom are actuated,
2. there are tracking tasks for locked coordinates, and/or
3. there are unnecessary control constraints on reserve/residual actuators.
