CMC wrong body distortion

Post by cui jiashuo » Thu Mar 14, 2019 10:46 am

Hello everyone, I used my own model to rebuild ik, id and rra, but when I did cmc, a warning occurred and my model was twisted together. I have posted the error message, which makes me very upset. I hope everyone can help me. thank you very much.

SimTK Exception thrown at InteriorPointOptimizer.cpp:261:
Optimizer failed: Ipopt: Maximum iterations exceeded (status -1)
OPTIMIZATION FAILED...


CMC.computeControls: ERROR- Optimizer could not find a solution.
Unable to find a feasible solution at time = 1.55.
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.
