MocoCasADiSolver does not support models with Controllers

Post by Md Asif Arefeen » Wed May 29, 2024 1:00 pm

Hello,

I am receiving the attached error. I am using OpenSim 4.5, and models with PrescribedController should work, right? (https://github.com/opensim-org/opensim- ... OG_MOCO.md). Could you please give me any suggestions on what could be the reason? Please note I am using MocoInverse.


Thank you,
Asif

Hi Asif,

The changes to support Controllers in Moco were introduced after we made the OpenSim 4.5 release. You are free to build OpenSim from source (or download a pre-built artifact from GitHub Actions) if you want to test the new Controller functionality, but note that these features will guarantee the same testing and stability as a full OpenSim release.

Best,
Nick
