## Thank you...

Thank you very much. But when I run the model, the simulation failed. If I cut the line between sine souce and custom component, the component works very well.

From the equations, the component's input is sin(2*Pi*t). If I want the component's input is an undefined signal, namely, u(t),then how can I do this?

Best regards.

## Hope...

Today I know about the acquisition. I hope maple will grow more stronger in the new year.

Best wishes.

Thanks a lot! You are right. I lost the ground block.

By the way, I upload a new picture. Can you tell me the answer?

Thesd days I find a command can solve my problem:

arrow(Vector([0,0,7*Pi]),Vector([0,0,-4.5*Pi]),1,5,0.2,cylindrical_arrow,color=blue,fringe=green);
