Good afternoon again,

I was looking through the data that's output from a forward dynamics simulation as done by the walking demo, but it doesn't seem to allow for the plotting of muscle-tendon complex length over time from the simulation. Is there a quick and easy way to calculate this value and display it in the plot tool?

Thanks,

Dan

Dear Dan,

You can plot muscle-tendon length for muscles in the current model during any motion (doesn't have to be a simulation) in the plot tool by picking
- muscle-tendon length for Y-Quantity,
- the motion of interest in the X-Quantity
- select the muscles you care about and hit "Add".

Hope this helps,

Hi Dr. Habib,

While those plots are certainly useful, one value that I'm interested in is muscle length during certain points in a movement cycle, such as a stride or a full revolution in pedaling. Normalizing it myself is no problem, but which values in the output files would I use to do this?

Thanks,

Dan
