Hi Quinten,
How did you solve this? I have the same issue.
Thank you,
Sanne

Calculating Joint Reaction Forces with Coupler Constraints
Hi everyone, I'm running a simulation with a modified dynamic upper extremity model to derive muscle and joint reaction forces (JRF) acting on the clavicle. The model contains several coupler constraints and I'm not sure how they influence JRF. Enabling or disabling the constraints during the comput...

Re: Warning: No suitable initial conditions found for
It appeared after I plotted the active and passive fiber force. I dubbel checked my muscleparameters and they look fine. I also checked the movement during when the excessive forces appear. Levator scapula lengthens a lot, that could explain the high passive force. But I don't see anything special i...

Warning: No suitable initial conditions found for
Hi everyone, I plotted the active and passive fiber force. I got a warning in the ‘messages’ window in the OpenSim GUI, which says that no suitable initial condition was found for delt2 and levator_scapula. they both have a high active fiber force and lev_scap has a high passive fiber force as well....

Re: Inputs for Adding Muscles and Ligaments into Foot/Ankle Model
Hi Michael, A colleague of mine is also working on the implementation of ankle ligaments (Tiago Malaquias). He is not participating in this workshop, but it might be interesting to get in touch with him. This is the link to his paper: http://www.tandfonline.com/doi/abs/10.1080/10255842.2016.1206533....
