I was tasked to construct the following 2nd order system in simulink:
y'' + 5y' + 6 = 0; y(0) = 0, y'(0) = 1
I have the following so far:
I'm not sure where and how I can input the y(0) = 0, y'(0) = 1 part.
I was wondering if I'm missing something or if this is correct already. Thank you!

Are you sure that differential equation shouldn't be: y'' + 5y' + 6y = 0 ?

Hi,
You are missing one more integrator block. Also you can specify the initial condition by simply double clicking both the integrator blocks and setting the initial condition to 0 & 1.
