Hi Thomas, Thank you for the feedback. I think I was indeed neglecting the force-length-velocity dependency. Although having zero velocity, joint positions define different fiber-lengths and thus different tendon forces, is that right? The algorithm I wrote was using the ideal force generators from ...

Hi Thomas, Let me first thank you very much for the time, the help and the references! Particularly, Zajac (1989) help me a lot to understand a bit better the mechanism. :) I have an initial application where the upper limb is statical (resisting an external force but without any motion). From the j...

Thomas, please apologize for my ignorance on the matter, my background is control/robotics :mrgreen: But, I was looking at the static optimization equations and it does seem to me that it only depends on the (i) joint torque, (ii) max. isometric force of each muscle, and (iii) the moment arm between...

Hi Chris, I guess the screenshot doesn't look very different from win or osx, but here it goes :) screenshot_2018_11_21.png ps.: sorry for the image quality (I had to reduce it). James, I'd be glad to help with the GUI repo. Let me first build a shell script with all these steps as Chris suggested (...

Hi everyone, I've just started using OpenSim and had a bit of a hard time installing the Gui. This post is just a resume of the procedure I did to make it work. Hope it helps others. :) INSTALLING THE API This should work without any problem. The detailed instructions are very well described at http...
