It is a mechanical system defined using the MulitBody mechanics library. I can't set any more initial position values to fixed otherwise the simulation fails.

Build log:

Warning: The initialization problem is structurally singular, error found sorting equations

Simulation Log:

[ERROR]: In initialization. System of initial equations is not consistent.

I am trying to pin down the initial velocities of loops to see if this might solve the problem.

Hi Neil,

I have been trying to fix the initialization values, it still finds the wrong initial solution. I have also tried to change the state variable selection, but it makes the simulation fail. I have tried different combinations of state variables and fixed initializations with no success.
