Re: how to calculate muscle force

Hello sir, i have reduce convergence torelance and increase mesh size then i am able to run analyze tool for Muscle analysis, so the result it is giving is active force , passive fibre force and fibre force , how i supposed to calculate total muscle force. Also now i need to add spring parameter as ...

Re: how to calculate muscle force

Also when i am using analyze tool I am facing issue.
a. when using analysis tool muscle analysis, matlab crash.
b. when using analysis tool , I get active force , fibre force , how to I get muscle force directly , and how I can calculate muscle force with these results.
