Transforming External Loads w/ Changing Kineamtics

Hi Folks, I am working on assessing how perturbations in hip kinematics alter joint loading during dynamic activities. Currently, I am generating a perturbed kinematics file by altering the hip abduction angle from RRA. To maintain dynamic consistency in CMC/Analysis tool, I am expressing the GRF in...

Re: penetrating surfaces between triangular meshes

Hi Josh, Did you ever resolve how to access the individual faces within a contact model using the API? I'm at a similar stage you were a couple years ago. I have successfully built an EF model, but now need to be able to query the overlapping mesh faces to calculate the contact pressure and am a bit...

Update Body for Muscle Origin

Hello, Is it possible to update the body that serves as the muscle origin in the .osim file? For example, I would like to update the <body> flagged as 'femur_r' to a new geometry named 'femur_dist_r' for an updated model that has the femur split into two segments. This could be done manually, but it...

Re: Obtaining Model Marker Trajectories

Tom,

Is there a reason that this file is not written when this setup file is called (with report_marker_locations set to true) using the InverseKinematicsTool from the Matlab API?

Thanks for your help.
