I am using Gait 2392 model to simulate squat motion, no solution was found by the optimizer for knee flexion angle larger than 60 degrees in CMC. I have tried increase reserve and residual forces, muscle strength, nothing worked.
Code: Select all
SimTK Exception thrown at InteriorPointOptimizer.cpp:262:
Optimizer failed: Ipopt: Restoration failed (status -2)
Thank you in advance,
Ruoli
