RRA/CMC tool fails
Posted: Tue Jun 11, 2024 1:28 pm
Hello,
I have been struggling to get the RRA/CMC steps to work (OpenSim 4.5). I'm attaching all input files for reference. I have not changed the default xml files (tasks, actuators, and constraints) that are available within the installed OpenSim gait2354 folder. The CMC tool works without the external loads file but generates an error when I add it.
Time range: 10.9533-12.04
kinematics .mot file
https://buckeyemailosu-my.sharepoint.co ... w?e=TJakBI
GRF .mot file
https://buckeyemailosu-my.sharepoint.co ... Q?e=lZDXgM
GRF .xml file
https://buckeyemailosu-my.sharepoint.co ... A?e=3DFzXr
model .sto file
https://buckeyemailosu-my.sharepoint.co ... w?e=jI6tJT
The error I get is: Tool execution failed or canceled by user. Output files were not written.
CMC::computeControls, t = 10.9533
SimTK Exception thrown at InteriorPointOptimizer.cpp:265:
Optimizer failed: Ipopt: Infeasible problem detected (status 2)
OPTIMIZATION FAILED...
CMC::computeControls: Optimizer could not find a solution.
Unable to find a feasible solution at time = 10.9533.
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.
Thank you!
