RRA Error
Posted: Fri May 16, 2014 11:13 am
Hi
I'm trying to run RRA, some of the trials went well and other trials receiving that error.
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 = 3.816.
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
I opened up the RRA_task, RRA_actuator and RRA_constrain files but I'm not sure which parameter I have to change to make the simulation run.
thanks
