Double Peak GRF's When Using A contact Model
Posted: Mon Aug 26, 2024 12:37 am
Hello,
I have been trying to run a 3D walking tracked simulation that is based off of the 3D walking example however I have replaced the GRF reference file with a six sphere contact model found here: https://simtk.org/projects/predictsim_mtp (see attached image for reference).
The simulation runs and solves well and has accurate joint angles but the GRF's are strange and the vertical GRF has 4 peaks instead of two (See attached image for reference). If anyone has any idea on why this might be occurring I would be very grateful to here it.
zip file with all the relevant files such as model, MATLAB code, and results: https://drive.google.com/file/d/1RROLqr ... sp=sharing
Thanks in advance.
