Hello, I want to know how can I get the end state from an integrator block and put it in as initial condition from another integrator block.
Both get the same initial condition , i want to get the end of the output value from the first integrator block as input for the second integrator block instead. I want to apply this for a in series-reactor set,so the output values from the first reactor are the input from the second.Thanks in advance

Please show the 2nd-order differential equation and supply the initial condition of the states, so that we can advise you how to properly construct the graphical model in Simulink.

Your use of a 1/s block instead of a 1/z block shows that you are using Continuous time. As such, all of the blocks theoretically run at the same time (unless you have delay-related blocks, which you do not have.) The algebraic solver tries to calculate ODE solutions that makes the blocks simultaneously consistent.
You therefor cannot have the output of the first block become the initial input for the second block: the two blocks are run at the same time.
It would be different if you had a delay-related block between the two. There are several delay-related blocks, but often the easiest to use is the Transfer Function https://www.mathworks.com/help/simulink/slref/transferfcn.html such as s/(s + 1e-8)
