Hello,
I have a question regarding the advanced muscle model,
AnyMuscleModel3E.
This model uses 3 elements, tendon, passive elastic element and
contractile element. If a muscle is pressed together (shortened) by
extern forces and is unable to generate force even with full
activation. How will the AnyBody system compute the separate lengths
of the tendon-unit and the contractile unit? Are them set to slack-
lengths or something else?
Thank you in advance,
Marie Lund
Hi Marie
As I recall it the tendon will be set to its slack length, in such a case.
If the muscles are compressed further the pennation angle will in theory
grow up to 90 deg, and if compressed even further the muscles model will not
attempt to calculate anymore and you will get a warning. Actually I think
there is some limit which will create a warning some time before the 90 deg
is reached.
Best regards
Søren
