Modify muscle properties

Main Forum

Hi everyone,

I 'm trying to modify the maximum force of the biceps brachii in the human model, but unfortunatly it’s not possible to change anything directly in the MusPar folder (It’s impossible to write anything). How can I change the F0 value of the muscle?

I hope someone could help me :slight_smile:

I thank you in advance

Hi Nadir,

It is correct that you should not change the F0 directly in the code, but you can change the value for your particular simulation without changing the repository. In the example below I modified the position of a muscle attachment, but you can similarly change the F0:

Hi Pavel

Thank you very much for your answer! I will try to do it :-).

However, I have another question, please.
If I want to modify the muscle model, from AnyMuscleModel to AnyMuscleModel3E (a much more complete model that takes into account the passive elasticity of the muscle and other physiological parameters).

Should I proceed in the same way?

I thank you in advance

Best regards
Nadir.

Hi Nadir,

In this case, what you could do is to exclude the original muscle from the analysis and include a more detailed one, possibly reusing the ref. nodes used for the original one. Here you can find a couple of different ways how one can exclude a muscle from the analysis.

Kind regards,
Pavel
