installation

I am installing the Opensim in Ubuntu system however while installing doxygen, it gets stopped at the message "Generating docs for compound SimTK::EllipticalPointContact..." I waited for nearly 3 hours but didn't move forward. What can I do? or is it normal for this process?


Thank you

Add ligament properties

I am adding ligament in the model and it has muscle properties. I have the equation that describes viscoelastic property of ligament. I was wondering if there is easier way to incorporate this equation without touching the source code


Thank you

Re: Plot change in tendon length

Thank you for your response however there is limitation in using this feature. In the motion file, I have data that provides the ankle position during landing. This angle increases and decreases rather than strictly increasing. I think this is causing the error in the plot. I was wondering if this i...

Plot change in tendon length

I have a motion file representing angle of ankle. I wanted to plot tendon change vs ankle angle from motion file. The normal method of plotting using tool -> plot... gives me data from ankle angle -90 to 90 degrees. My motion file contains ankle angle 0.07 to 0.45 radians. How can I plot tendon leng...

Problem with muscle addition

I have added a new muscle (Thelen2003muscle format) and also included in reflex controller so that it can be activated at appropriate ankle movement. However when I run the simulation, the plot shows 0 value (no change) in muscle length or force with respect to ankle movement. I would like to know i...

bvh File implementation in Opensim

Hi,

I am new to Opensim and would like to know if I can utilize bvh file in Opensim model motion. As per my knowledge and research currently there are no tools developed for converting bvh file to mot file that I can implement directly.

Thank you for your help and advise

I would also like to know minimum standards that needs to be met for publishing OpenSim Models. I would be happy to further clarify my question if...
