Dear Colleagues,

I am writing this e-mail to inform you about public access to a modeling
framework developed for a coupled musculoskeletal lower extremity model
and finite element representation of a foot, which was recently made
available by our research group. The framework was developed as part of
a project to develop efficient methods for multidomain biomechanical
simulations. In brief, a surrogate modeling scheme was adopted for
efficient estimation of the underlying finite element foot model. As a
proof of concept, a computationally intensive optimal control scheme was
used to maximize jump height of the coupled model [1]. Interested
parties can access the modeling components including the compiled
musculoskeletal model, generic 2D finite element foot model, and
surrogate model interface.

We believe that this modeling framework can be a valuable resource for
those interested in multidomain simulations of musculoskeletal movement
and tissue deformation models. It will hopefully encourage future work
in coupled modeling by facilitating access to an efficient surrogate
modeling framework.

Access is at the website:

https://simtk.org/home/multidomain

through the section labeled as "Jump Optimization" under "Downloads".

Please feel free to contact us for any questions. Your comments are more
than welcome.

Best Regards,

Jason
