Hi Allison, We generate our knee joint contact force predictions by applying experimental GRFs to the foot during an inverse dynamic simulation. I now realize that the absence of this data may have been by design to encourage participants to explore alternative approaches...?! I will explore using a...

Hi Allison, My question is in regards to the Yr5 right turn data. I know you guys have done an excellent job making sure the data is correct and accurate, yet I sill have an issue that someone might help clarify. When I view the GRF data for the right turn trial #6 (PS_rightturn6_grf.xls), I see onl...

Hi Derya, You will likely need to use a number of different programs to create your cat model. I've recently created a sheep hindlimb model from scratch and am now in the process of refining and validating my work. To create my bone geometry files I used a program called Amira to convert a CT scan o...

Thanks Sherm, this will be very helpful.

Using the API, I'd like to implement an OptimizerSystem that specifies both an objective function a constraint function. Using the arm optimization example as a starting point, I've been able to implement a OptimizerSystem with an objective function, but now I'm a bit lost trying to implement the co...
