I am trying to model a parallel manipulator but I am receiving an error message
State variable'diff(diff(`Main.R41.theta`(t),t),t)' does not appear in dynamic or constraint equations.
I tried changing the Revolute joint 41 but the same error is repeated.
You can find my model here: ParalelManipulator_v2.msim
Can you help me solve this issue? Thank you in advance!
