New Features in the AnyBody Modeling System 8 0

Join us for a tour of the new AnyBody Modeling System 8.0 and the included updated AnyBody Managed Model Repository 3.0.
We will guide you through this major update which includes several new features and improvements that will enhance your modeling experience. AnyBody 8.0 introduces new AnyScript syntax, new meshed surface classes with related volume measures and inertia modeling classes, enhanced ligament and fatigue modeling, and a new update engine handling symbolic dependencies in all simulation operations and supporting many new AnyScript functions. Additionally, we have made improvements to the graphical user interface, in particular the Model Tree and Model View, and added support for recent Python versions (3.12).
The AnyBody Managed Model Repository includes several important updates and improvements. The highlights include the integration of pelvis, lumbar, and thorax models into a consistent trunk model, and updates to the leg model (TLEM 2.2) with improvements to the ankle complex, alignment of the patella tendon, and new wrapping surfaces to the Achilles tendon

Lots of good stuff here. It is great to see so many new developments and features.

Lots of great additions here. Id there anyway of adding dynamic Spinal Rhythms (i.e. ones that change depending during motion)?

[@MortenEnemarkLund]

Great question. That is possible, and we already use this trick for the flexion/extension rhythm. Here the coefficients change between between two sets of coefficients. A sort of bi-linear rhythm. One set of coefficients for flexion and others for extension, with a smooth transition between these. It works using an interpolation function. For the bi-linear flexion/extension rhythm the interpolation function built from two straight lines with different slopes. One for positive and one for negative inputs.
The bi-linear rhythm is easy enough to uses, but the underlying AnyScript implementation is bit more convoluted. It seems I can't post links here, but if you ask the same question on the AnyScript community forum, then I may be able to give you some more help on how to do this.

I wish you will do some work with paleontologists and help study hominin locomotions and investigate extinct hominin skeletal morphology/anatomy. This looks a neat tool for research in so many ways! 🤙

Hi, there has actually been some work along those lines. I believe you will find this webcast interesting: ua-cam.com/video/c3DtQGWaFnA/v-deo.html (Musculoskeletal modeling for the evolutionary biologist: A primer) or this recent publication: Sylvester A, Kramer P, (2024), "Achieving kinematic identity across shape diversity in musculoskeletal modeling".
