Hello,
I am trying to attach a unidirectional clutch to a revolute joint using a multibody rotational interface and a rotational reference however this doesn’t seem to work.
What happen is that the "disengaged phase" goes well but at the moment the relative velocity between the hub and the ring changes direction the simulation crashes with the following message :
An error occurred during simulation and the simulation was terminated
Caused by:
[‘Modele_RZ/Solver Configuration’]: Transient initialization at time 1.903, solving for consistent states and modes, failed to converge.
Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix.
The model may not give enough information to make it possible to solve for values of some of its variables. Specific advice is given below.

all components and nodal across variables involved
Cannot solve for one or more variables:
‘Roue_Libre_Haut_Avant.Rotational_Multibody_Interface.t’ (t)
‘Roue_Libre_Haut_Avant.Rotational_Multibody_Interface.torque’ (Torque)
‘Roue_Libre_Haut_Avant.Rotational_Multibody_Interface_t0’ (Rotational_Multibody_Interface_t0)
‘Roue_Libre_Haut_Avant.Unidirectional_Clutch.fundamental_clutch.clutch.t’ (Torque)
‘Roue_Libre_Haut_Avant.Unidirectional_Clutch.fundamental_clutch.torque’ (Torque)

I have tried a bunch of modification but nothing seems to work…
I would appreciate a bit of help.Hello,
