Hi,
I have scaled a full body model (changed femur length) using manual scale factors and found that the optimal fiber and tendon slack lengths for both unscaled and scaled models remained same. Can someone please help me understand what might be the issue?
Thanks in advance.

Re: muscle properties remained unchanged in a scaled model
Hello,
I am having a similar issue utilizing the gait2392 model. In my muscle analysis results, the MTU length changes due to the shift in tendon lengths and properties; meanwhile, the muscle fiber lengths remain the same for all muscles (0.10). This is also strange because the muscle fiber velocity outputs are also changing throughout the duration of the trial. Is there something regarding the muscle properties that leads to the length parameter to be fixed? Has anyone run into this issue before and resolved it? Any help or tips are appreciated--thanks!
