I have just posted an issue in regards to kinematic analysis. I am still on the same mission, but this time I got an error while analysing inverse dynamics. I will repeat the background information of this task for you here:
Seventeen subjects have been recorded by Xsens MVN Awinda inertial motion capture system with 17 wireless motion trackers and an update rate set to 60 Hz.
I am interested in estimating the Ground Reaction Force out of the BVH files. Here, the Xsens T-pose is in the beginning of every BVH file I am going to analyse. Thus, I was loading the inverse dynamic model, running the BVH_PreProcess and started to run the analysis. Some estimations succeeded, others resulted in errors.
While running the analysis on one subject I got a failure in factorization of stiffness matrix for velocity analysis during inverse dynamic analysis.
Please find the corresponding screenshot attached.
I am happy about any help.
Many thanks and best regards,
