Hi Everybody,
a question concerning the viapoint-nodes for the viapoint-muscles.
Are through these nodes applied any forces to the segment on which
they’re positioned, e.g. origin segment 1, viapoint on segment 2, and
insertion on segment 3?
Thanks for your help,
Best regards,
Alex
Hello Alex
On the muscle model tutorial side: http://www.anybodytech.com/686.0.html
it says the following:
Via point muscles pass through a set of at least two points on their
way from origin to insertion. Each of the via points must be attached
to a segment or the global reference frame of the model. The first and
the last of the point sequence are special because the muscle is
rigidly fixed to them and hence transfers forces in its local
longitudinal direction to them. Conversely, the muscle passes through
the interior via points like a thread through the eye of a needle.
This means that the muscle transfers only forces to interior via
points along a line that bisects the angle formed by the muscle on the
two sides of the via point.
I hope that answered your question.
Best regards
