Hey, did you ever get this to work? I am also trying to simulate 4 external forces and only 2 are showing up? Thanks!

Hey everyone! I am currently working on modelling eccentric cycling and there are 4 forces to be modelled in my inverse dynamics (backrest force from bike setup, seat force from bike setup, and two foot forces from the pedals). When running the ID with just the back and seat forces, the external for...

Hi Nicos,

That is very helpful thankyou!

Cheers,

Hey does anybody how to get the model marker positions? I don't want the angle, but rather the coordinates (e.g. x,y,z) of particular markers of interest. I have seen it may be possible in the "Tools," "Analyze," "Analyses," "Point Kinematics," "Add," "Point Kinematics," and then click and edit, the...

Hi Thomas, do you know how to get the coordinates (x,y,z) to input into the 3 positions in the point kinematics tool? Thanks

I am using OpenSim 4.4 and am having issues with my external forces. I have written a .mot file in MATLAB for a person cycling (looking at only grf for feet at the moment) based off torque data and moment arms etc. This has given me a ground_force_vy and a l_ground_force_vy. All other forces an torq...
