myology lab — build a muscular system, solve its stability

Attach muscles to the skeleton's nodes (joint centres, bone ends, neural-spine tips) and press Solve for a structural force solve: the pull-only tensions that balance every joint's buckling torque, plus the ground reactions. Too few muscles ⇒ no solution ⇒ it crumbles. Or hit Auto-grow to let the solver build a whole musculature, spine and all.
press SOLVE
joints balanced—
CoM over support—
muscles · total force—
over capacity—
balanced joint   unbalanced (buckles)   CoM
tension (brighter = harder pull)   over capacity   ↑ ground reaction
Add a muscle: click Add, then click two skeleton nodes. The dorsal (spine-tip) and ventral nodes set the side and lever. Solve shows the forces; with no muscles it crumbles.
