How to save Simulink Simulation output and runs it sequentially (creating a database)?

Hi everyone!

I have a Simulink Simulation that has two blocks To Workspace, exporting two variables: Ir and Fault. How can I create a script that calls my simulink simulation and save these outputs sequentially, like Ir1, Ir2, Fault1, Fault2 and so on.

I tried:

function save = postsim(out);
for i=1:2
Save('Ir','Fault');
end
end

and:

in = Simulink.SimulationInput('MyModelName');
in = in.setPostSimFcn(@(Fault) save(Fault));
in = in.setPostSimFcn(@(Ir) save(Ir));
in = in.setModelParameter('SaveOutput','on');
out = sim(in);

And I get:
