Re: CMC still failing on non-muscular model

Sietse and I have been in touch through e-mail but I am writing a short summary here for our community. (1) kinematic loop requires only one of the determining degrees of freedom to be in the tracking tasks (adding more makes CMC crash immediately). This was mentioned in a related post as well by Ni...

Re: Seeking Assistance with Real-Time Inverse Kinematics Implementation in MATLAB using OpenSim

Hello Hoon, If you really want to have everything contained in Matlab there are at least two options: (1) use fmincon/fminunc in combination with the API. The coordinates are optimization variables for fmincon and you use them to set the model (with markers) in the corresponding pose through the API...

Hunt Crossley Model : slow numerical integration

Hi, I noticed something happening in the Hunt Crossley Model that I can't understand completely. I have an adapted gait9musc18 model with 2 spheres in both feet and a half space in the ground as contact geometries. I am running a forward simulation with this model giving it some (random) activations...

Re: Can a body have 2 joints?

In order to do predictive simulations I want to build up a model from ground via the feet up to the torso. This means (in topology view) that I do have to create a loop (that comes together at the pelvis) and I will try it like James and Michael have suggested. I am now trying to understand how the ...
