Force Equation Not Functioning Correctly

[Rose Newberry]

My lab is running tests on the effect of adding a pulley and ligaments to the fdl to double its force output. In the code, the max isometric force of the fdl is 274 N. When I run forward dynamics and plot the forces in the fdl and the added ligament, it shows a mean of 560 N in the fdl and 1045 N in the ligament. I think it has something to do with the pulley because it's a wrap object, but I'm not really sure how it works because I got this code from a coworker. It's somehow doubling the fdl force before it gets to the equation for the ligament so that we get double the max isometric force in the fdl, and then that is doubled again in the ligament.

The maximum isometric force only takes into account the active component of muscle. Have you checked the passive component and its contribution to the overall force?
