I have learnt to use Opensim for analysis of human walking for a few days, now I have a problem about the results of model RRA. I have adjusted the markers to make the IK error in good situation. and the external forces are also corrected.But I still have the poor results of RRA: After torso COM and Kinematics adjustments:
* FX=15.9576 FY=101.391 FZ=37.9502
* MX=7.33893 MY=-8.43846 MZ=3.19413
but I really cannot understand how to improve the results.
please give some suggestions about the problem, thanks a lot.
Best regards
