Static Optimization

[2453828936]

Has anyone successfully run OpenSim Static Optimization with this musculoskeletal model? I've set the actuator strength extremely high, but it still doesn't converge.

Hi, I haven't personally, but you might have more luck asking:

• the Pose2Sim Discord community: https://discord.com/invite/4mXUdSFjmt
• the OpenSim forum (as the model and IK do not differ much whether they come from markerless or marker-based analysis): https://simtk.org/plugins/phpBB/indexPhpbb.php?f=91

Does your animated skeleton look okay to you? It might help the people if you share the .osim and .mot files, as well as a short video of it.

I'm using the file calculated in your example. Demo_SinglePerson_1-98_filt_butterworth.mot ,Demo_SinglePerson_1-98_filt_butterworth.osim . and actuators.xml

I don't have much experience in static optimization, I can try but probably not before 2-3 weeks (Christmas + article submission rush).

Did you post the issue somewhere else? I'd you get an answer, I'd be interested if you posted it here!

Thank you for your reply. I've posted a question on the OpenSim forum and am waiting for a response. In any case, if I find a solution, I'll share it here.
