Recommended setup/modifications to optimize forward dynamics?
Hi all, thank you so much for your work on this model. I have been reviewing some of the forum posts and wanted to seek any input on potential implementation of this model for forward dynamics simulations. I am hoping to run some forward dynamics/contact-based simulations with a focus on the spinal ...

Elastic Foundation h value adjustment?
Hi everyone, I have some EF contacts built into my model and I am wondering if anyone can help clarify if there are any methods to alter the thickness (h) of the elastic foundation force calc. My understanding, when looking at the previously published paper by uchida outlining this contact, is that ...

Re: .obj fail loading
Hi there, please check your settings in opensim under edit preferences. paths: geometry searhc path. it is probs trying to find the files there. copy your obj files into this directory or change the directory pathing

Error when trying to run forward dynamics in a different pose
Hi there, I have changed the coordinates of this model to match a specific pose that I am aiming for, and I am attempting to use the forward dynamics tool. I am getting this error: Integrating from 0.0 to 0.5. ForwardTool::run() caught an exception: Exception caught in Millard2012EquilibriumMuscle::...

Unexpected elastic foundation interaction with varying stiffness
Hi everyone, I currently have a model which includes a polygonal mesh and a sphere (for now) interacting with said mesh. These are both set to elastic foundation forces with default parameters. The mesh body is 40kg and the sphere is set to 1kg. With the default EF force parameters, I get expected i...
