Unit of muscle activations / how to get true forces?

Hi everyone,

I know that I can access the computed muscle activations after running inverse dynamics from the HDF5 file under the Path /Output/BodyModel/Left/Leg/Mus/{Muscle}. But what is the unit of those trajectories?
Are they dimensionless normalized muscle forces?
What must be done in order to obtain the forces in Newton?

Thanks and best regards
Felix

Hi Felix,

It sounds like you are going the hard way.
Muscle activation is a current muscle force divided by the muscle strength (max force). Please revisit the tutorials: “Inverse Dynamics of Muscle Systems”

Kind regards,
Pavel

Hallo,

i’m sorry but i’m trying to post a thread but it is always invisible. i send the admin and the senior member private messages but still no reply.

is there any kind of support here ??
