Issue with coupled coordinate
Posted: Fri Jun 22, 2018 5:17 pm
Hello,
I used recent compiled OpenSim 4.0 from source (version 4.0, build date 14:29:51 Jun 6 2018).
Then, I found an important issue on angular displacement with coupled coordinate.
I posted similar issues on GitHub (https://github.com/opensim-org/opensim-core/issues/2208).
I prepared two sample files: Linear (use linear function for custom joint) and Couple (use SimmSpline for custom joint).
Then, the output of state variables look like radian for Linear and degree for Couple. I think couple coordinate turns meaning of input or definition angle values from radian to degree.
Hopefully, OpenSim may have consistency in rotational unit.
Thank you and Best,
Hide
