Spring types on Opensim

Hello, I am trying to link an otrhosis to the lower limb of an OpenSim model. As my aim is to simulate the most realistic interaction between the leg and the orthosis I was thinking of implementing a spring, which properties would be able to mimic some kind of skin and soft tissue movement. I do not...

Re: Static optimization returning incorrect info

Hello Dimitar, So what will happen if I remove all the CoordinateLimitForces and the ConstraintSet from the model? If the problem is in those elements and I remove them SO should work. After removing them with Notepad I can open the model, block all the coordinates that are not interesting for me an...

Static Optimization problem MoBL Arms Model

Hello, I have a problem with static optimization on MobL Arms Model. The files I am using are: - A motion file which represents a shoulder elevation (shoulder_elv) from 0 to 90, the other coordinates are all blocked because I am interested only in studying the effect on Deltoid and Latissimus Dorsi ...

Passive Devices (Spring Parameters)

Hello, I am trying to add a passive aid walking device to a model to simulate the influence of the ankle device on gait and muscles involved in it (mainly gastrocnemius). I am performing several trials with different parameters of stiffness, damping and transition but I do not understand the values ...

Re: Coordinates Visualization

Thank you for the answer Dimitar. After performing the coordinates removing by defining WeldJoints among joints I have faced a new problem. In my case I was interested in removing all the coordinates except 3 defining the torso movement: lumbar extension, lumbar rotation and lumbar bending. My probl...

Coordinates Visualization

Hello, I am trying to modify some OpenSim models for integrating them with C++. My aim is to simplify a model, so when it is executed through C++ I can visualize only some of the coordinates of the whole model for an IK and ID process. My question is if it is there any way to hide a coordinate in th...
