How run Simulink model automatically from itself if a condition is met?

I need to run simulink twice automatically only after the first run (this is because I need the data from the first simulation in order to feed the next one - this already works in my model by an InitFCN code).

I tried implementing the next code in StopFCN callback, but obviously it doesn't work because "Termination of 'model_name' is in progress"

%no. runs counter
Number_Runs=Number_Runs+1

%only if number of run times is 2 automatically run simulink
if (Number_Runs - 1)==0
 sim(SIMULINK_MODEL_L7);  %%HERE IS WHERE I TRIED TO RUN BY CODE
end

I can't come across any solution to implement this.

Hope I explained well.

Try it in PostSaveFcn, or have an independent and separate M-script to control your simulation.

Thank you Fangjun, I tried in a separate M-script as you told me, by

sim(SIMULINK_MODEL_L7);

But before executing it for second time, it appears the error:

'model' parameter must be a character vector

I do not need any simOut because I save to Excel every output simulink variable in the callback StopFCN (by calling another M-script).

What can I do?

Many thanks

Might it be just a simple syntax error, like

open_system('f14');

sim('f14')

or you could do

model='f14'

sim(model)

Thank you Fangjun, it now works propertly with:

open_system ('model_name');
sim('model_name');

(Although I had already manually opened the simulink window, it turns out that it needs anyway the "open_system" command in the M-file).

Thank you again.
