Re: high reserve actuators
I am experiencing a very similar issue and hoping that we can all find a solution so I am posting this here. This is my summary of this issue/the possible solutions: If a simulation is unable to converge, only converges with high reserve actuators, or saturates the muscles (maximum activation an/or ...

Re: Append/Prescribe vs. Tracking Ground Reaction Forces
That makes sense. Thank you, Nick!

Re: high reserve actuators
How many parameters did you optimize with problem.addParameter()? I tried to do the same with 3 parameters each (max isometric force, slack tendon length, and optimal fiber length) 15 lower-body muscles and the overall simulation was so slow that I didn't even try to let it finish converging.

Re: high reserve actuators
Hi Christian. Unfortunately, I don't have an answer for your reserve actuator question but I was wondering if you could share how you did parameter optimization on the right ankle-foot muscles before the MocoStudy? Was that optimization within Moco, using an OpenSim tool, or with your own process? T...

Append/Prescribe vs. Tracking Ground Reaction Forces
Hello! I am working on a Moco tracking problem with experimental data of transtibial amputees walking with powered prostheses. We are trying to track the joint angles, GRFs, and prosthesis torque. I was wondering if anyone had any thoughts on appending/prescribing vs. tracking the ground reaction fo...

Re: MocoAccelerationTrackingGoal & MocoAngularVelocityTrackingGoal Failing to Transfer Reference DataTable to Solver
Hello! Thank you all so much for your hard work on Moco. I am joining this thread because I have a very similar question and Owen's setup of the problem was very clear. However, I am a step further behind Owen and am struggling to figure out the format for acceleration reference data. I am trying to...
