I am looking for options for co-simulation within simulink.
Scenario: I need one subsystem in simulink to run for 60 sec and send the average result (lets say 'a') to next subsystem, which takes 'a' as input and will continue the simualtion for 600 secs. How can I do that with in simulink?

I would put each subsystem inside an Enabled subsystem, and enable the second subsystem after the first subsystem had finished and the result is averaged. The first subsystem can then be disabled and its outputs set to 'Held' to fix its outputs.

It sounds to me that the easiest way is to set up two Simulink simulations. Save the output from the 1st one to the MATLAB workspace, so the 2nd simulation can use it as the input. You can also use MATLAB code to manipulate the result form the first one, say taking average. Use out=sim() function to run the Simulink models from script.

To make it clear,
I have to make two sim models, make a main MATLAB script and run 'model a' , store the results and then run 'model b', right??
