How to create a closed loop with initial solution

I would like to create using Simulink a closed loop system in which i provide the initial solution to start the simulation and than the model has to do a loop every dt (es. 0.05 s) using the solution of the previous loop. How is it doable?

You can feedback your previous result using a delay block or memory block.

The intial condition for either of these blocks can be set by double clicking on it.

thank you for the perfect answer! is possible to control the number of loops? for example can I impose the model to do 1 cycle per second?

Try the "Unit Delay" block instead of Memory. You can set the sample time to be every 1 second.

(Depending on what you need to do, another simple option may be to change the solver in the Configuration Parameters to Fixed Step and set the step time to 1 second.)
