Hello,

You need to add the necessary blocks to represent your system and the excitation force. These blocks might include:

• Source Block: Use a source block to generate the excitation force. Common choices include:

Sine Wave: For harmonic excitation.

Pulse Generator: For pulse excitation.

Step: For step input excitation.

Signal Builder: For custom signal shapes.

• Gain Block: To scale the force if necessary.
• Sum Block: To add the force to your system's input.
• Scope Block: To visualize the output.

Now, double-click on the source block you chose to set its parameters (e.g., amplitude, frequency for a sine wave). Connect the output of the source block to the rest of your system. Use the "Sum" block to add the excitation force to other inputs if needed. Once everything is connected, run the simulation to see how the system responds to the excitation force. You can adjust parameters as needed to refine your model. You can use the "Scope" block to visualize and analyze these results.

Hope it helps!
