attempt to a nil value

Post by Samane Amini » Sun Aug 07, 2022 6:49 am

I would like to get some info from muscle:
active_fiber_force()
active_force_length_multiplier()
passive_fiber_force()
...

Scripting the following code shows this error "attempt to a nil value ":

F = model:find_muscle("rect_fem_r"):active_fiber_force()

Would you pls guide me on how to get it?

Kind regards

Are you using the latest version of SCONE (2.0.6)?
