How can I draw a basic differential equation in Simulink?

Click For Summary
To create a basic differential equation in Simulink, the user is attempting to replicate a specific equation but is struggling with the implementation. They referenced a MathWorks blog for guidance but found it unhelpful, particularly when trying to connect their setup to an XY Graph. Despite following the example, they are not achieving the desired output and are unsure of their mistakes. The user seeks assistance to correctly model the differential equation in Simulink. Clarification on the setup process and troubleshooting tips are requested.

Homework Statement



Hi,

I was wondering if someone could help me create a basic differential equation in Simulink. I'm trying to create the following equations

I tried using this as an example http://blogs.mathworks.com/seth/2008/05/23/how-to-draw-odes-in-simulink/ ODE to help me solve this problem but it doesn't seem to help. The link above has a very similar ODE. When I create two of what is done in the example and try and connect it to a XY Graph I don't get anything so I'm doing something wrong but am not sure what. Thanks for any help.
