Hi, getCoordinateNamesInMultibodyTreeOrder can be used instead:
Hope this helps.

Hi Nicos, please find the attached files:

Hi, this might be a stupid question. I created the GRF file with ForceLocation set to zero (forceplate origin) and one (COP). This is the output which makes sense: COP.png Then I executed Inverse Dynamics for each file. My question is why the outputs are exactly identical? Moment.png It seems that t...

Hi, this is a bug, I posted it on the GitHub page for the record: https://github.com/opensim-org/opensim-gui/issues/1529 Must wait until the developers fix it. In the meantime, there is a workaround for this bug: After creating the XML analyze tool through API, a simple code can be used to replace t...

Hi, sorry for brevity. Free coordinates are independent without any constraint, so the optimizer can change their values. The Coordinate::isConstrained method could help you find them; for example in Python: import opensim as osim model = osim.Model('Rajagopal2016.osim') state = model.initSystem() f...
