Find the point where muscle tough the wrap object

Post by Yichen Huang » Thu Oct 24, 2019 4:31 pm

Dear OpenSim users,

I am new to OpenSim, and I am currently trying to build a finite element model of glenohumeral joint in Abaqus.
To do that, I got the muscle forces from OpenSim and plan to model these muscle forces in Abaqus.
But there are different kind of muscle geometries. The simple ones are just a straight line or several straight line segments. As shown in attachment file 1.PNG. These kind of muscle is easy to model in Abaqus.
But some of the muscles wrap around an WrapObject, as shown in attachment file 2.PNG.
What I want to do is finding the point where the muscle touch the WrapObject, so I can go on to model these muscles in Abaqus.
Could someone provide some advice on this?
Thanks a lot!

Best regards,
Eason

Please see topic 7831 (https://simtk.org/plugins/phpBB/viewtop ... =91&t=7831). The code I provided there might be helpful.
