Re: Defining Joint Motion using Generalized Cordinates
Hi Dimitar, Thank you for your reply. In my case theta and p are independent of each other as I am prescribing motion from located position to dislocated position for humerus. Do you think is there any way to implement this eg (modelling 6 DOF with 6 different joints at the same location and prescri...

Defining Joint Motion using Generalized Cordinates
Hello Everyone, I am using 6DOF custom joint between scapula and humerus to stimulate dislocation. I have generated trajectory in Matlab i.e. translation XYZ and rotation Euler angles. Opensim requires generalized coordinate as an input for prescribing joint motion. Does anyone know how I can implem...

3D Rotation Matrix
Hello, I have been using custom joint between humerus and scapula, I have generated the trajectory of the humerus in matlab using 3D rotation Matrix( see the attached file). When I use those trajectory to rotate humerus in opensim, it rotates completely different , I don't know whether I have to con...

Prescribed_Function_error
Hello, I am trying to use prescribed function to move the coordinate joint in the desired position using FD tool. I have been using <PiecewiseLinearFunction> <x> 0 1 2 3 4 5 6</x> <y>0.054530 0.193382 -0.0007 -0.00630 0.01611 0.02281 0.02328</y> </PiecewiseLinearFunction> After running the FD tool i...

CustomLigament_Plugin
Hello,
I am trying to use custom ligament plugin from"ACL Reconstruction Decision Support Through Personalized Simulation of the Lachm" Project.
There is no .dll file for plugin to use in the download section. They have .rar file, any possible way to use .rar as plugin?
Thank you!
Regards,
Rahul

Forward Dynamic _result error
Hello Everyone, I have created a shoulder model having path spring (i.e. Ligament) attached to the shoulder. I am using prescribed function to move the joint by running the forward dynamics. Simulation runs for the defined time period (i.e. 4 sec) without any error, but the body segment attached to ...

Re: Importing .stl file
Thank you for your reply.
The scale is set to 1 1 1. Changing it to 0.005 0.005 0.005 make it look reasonable with coordinate axis of opensim.
Scaling it 0.005 does not make sense since the geometry becomes extremely small.
Any suggestion what can I do ?

Importing .stl file
Hello All, I have an query when I import the geometry (.stl) having length of 314 mm in opensim, the visual coordinate axis in opensim goes extremely small. It makes me feel the geometry is extremely big but it is not. Can anyone tell me the potential problem for this and how to solve that. Thanks i...

Re: Potential Energy of Ligament
Thank you for your response. I know I can customize the ligament, but I don't know what input function (xml) are required in the model to get potential energy (P.E.) from FD tool. Something like below will work? <SystemEnergyProbe> <!--Flag indicating whether the Probe is disabled or not.--> <isDisa...
