The model:

<</matlabcentral/answers/uploaded_files/27438/3.PNG>>

The simMechanics system is as follow:

<</matlabcentral/answers/uploaded_files/27436/1.PNG>>

simin is input from workspace and is the motion of Revolute Joint as the time goes on.

<</matlabcentral/answers/uploaded_files/27437/2.PNG>>

But it shows some kind of error:
In the dynamically coupled component containing Revolute Joint Revolute_Joint, there are fewer joint primitive degrees of freedom with automatically computed force or torque (0) than with motion from inputs (1). The prescribed motion trajectories in this component may not be achievable. Solve this problem by reducing the number of joint primitives with motion from inputs or increasing the number of joint primitives with automatically computed force or torque. Resolve this issue in order to simulate the model.

Does anybody knows what’s wrong and what should I do to solve the problem.The model:
