Joint force equations

[nathalie]

Dear anyBody Team

I was wondering where I can find the equations that are used to calculate joint contact forces within the AnyBody lower extremity model?

I'd appreciate your help.
Thank you and kind regards,
Nathalie

Hi @nathalie

The equations are part of the inverse dynamics algorithm and therefore not accessible to users.
To better understand the equations and how we solve things here are a few publications:

• Introduction to musculoskeletal modelling - ScienceDirect
• Analysis of musculoskeletal systems in the AnyBody Modeling System - ScienceDirect
