Hi Michala, Thanks for your reply, and sorry for the late (I didn't check the "Notify me when a reply is posted" square) I am using Vasavada Neck model fo find muscle activation for different movements (extension, flexion, rotation, etc.) And I would like to add the hyoïd bone with its muscle on the...

Hi Michala,

I am also looking for this geometry. Have you found it during your research ?

Cheers

Pierre

Hi Nicolas,

I am working with Opensim 3.0, I believe that's why nothing happens. Thank you for your reply!

Best Regards
Pierre.

Hi, I am on Windows 7 64 bit, and I did not managed to launch it. I can read in the instruction : " 6) Start OpenSim. Nothing should changed, then exit OpenSim. A NetBeans window should appear very briefly, loading the module. OpenSim will restart automatically with the module installed and ready (a...

Hi Ayman and all, Ayman, thank you for your answer. Following Opensim gaitmodel Actuator's structure, I created 6 "CoordinateActuators" corresponding to my 6 DOF, and I append them to my osim model. Then my StaticOptimization worked at last. This is an example of one of my actuators : <CoordinateAct...

Hi everybody, I am using the Vasavada’s neck model, and I am trying to perform Static Optimization (SO). Nevertheless, in most cases, the optimization does not succeed because the muscles are weak, and that’s why my SO takes always a very long time to converge (or sometimes never converge at all). M...

Hi Caterina and everybody, I think I have exactly the same problem. Did you manage to find a solution? I am using the Vasavada’s neck model, and I am trying to perform Static Optimization (SO). Nevertheless, in most cases, the optimization does not succeed because the muscles are weak, and that’s wh...

Hi everybody, I am using the Vasavada's neck model, and I would like to perform Inverse Dynamic. Nevertheless, there are in this model any mass and inertial propreties. Then I tried to take the full model to take theses informations, but some groups are already made. Ex : the segment "torso" is cons...

Hi Ayman and Thenia, Ayman, thank you for the description of theses differents cases. For my part, it was a problem of mass and inertia propreties. I am currently fixing it by addind mass, mass center and inertia matrix in the joint file. I will tell you what I will find out when I would have comple...

Hi Ayman, Thank you for your help. Endeed, optimization on each frame failed, even if it is not written clearly ; here there are the results which appear on the message box : --------------------------------------------------------------------------------------------------------------------- Old ver...
