In my model, both ports of a "Disk Friction Clutch" are fed in with equal angular velocities using "Ideal Angular Velocity Source" blocks. When the clutch is locked, i.e. the control pressure signal value exceeds the Engagement threshold pressure, the model errors out with the following message:
An error occurred while running the simulation and the simulation was terminated
Caused by:
- ERROR: Trouble solving algebraic equations in differential-algebraic system. Singular iteration matrix encountered with step size 0.2 at time 0.0. Try tightening the error tolerances. If the problem persists, check the model structure and values of parameters.
However when the difference in speeds is significant, the model runs fine. Why can't I specify equal velocities as inputs to the clutch?
