Deformation of the model when i used RRA

Provide easy-to-use, extensible software for modeling, simulating, controlling, and analyzing the neuromusculoskeletal system.

Deformation of the model when i used RRA

Post by Valentin Bertucchi » Mon Jun 25, 2018 6:30 am

Hello, i have a problem with my model.
I have data of a software of motion capture, and also data of ground reaction force.
When i try to do the RRA (after scaling, IK, ID...), they're an error, my model are deformed at 0.071 s (when the model putting on the foot in the force plateforme);
The RRA turn with deformation of the model but the final average is very bad :

* After torso COM and Kinematics adjustments:
* FX=-120.464 FY=2935.32 FZ=-743.063
* MX=-23.0271 MY=32.3474 MZ=75.7855

Do you have a solution to avoid this deformation of the model ?
Thank you for answering,
Best Regards,
Valentin Bertucchi

Hello,
i changed in the settings of the "RRA Control Constraints" the datas for interpolate. I replaced the boundary "-1 to 1" by "-5 to 5" and also i changed the "FX.excitation" to 1000 at 3000. With this modification, i don't have any problem with a movement of deformation of the musculo-skeletal model but with the other tool : CMC, i have problem... can you help me ?
Sincerely,
Valentin B
