sim('') command with supressed ";" still displays a variable on command window (it's spamming it)

I am currently trying to run a number of different load cases in a simulink model, and I thus use the "sim('model')" command in a for loop. My code is seen below

LoadCases = [30, 31];    
idx = 1;
for i = LoadCases
    LoadCase = i;
   	sim('WPSCMM82_IEC_Simulations_V009_lima_23_nov_2020');
    KeyData{idx} = KeyDataDisplay.signals.values(end,:)';
    for k = 1:size(KeyDataScope.signals,2)
        scopedata(:,k) = KeyDataScope.signals(k).values;
    end
    TimeSeriesData{idx} = scopedata;
    idx = idx + 1;
end

Where LoadCases is the variable in the simulink model I change for each loop. The data variables are just used for logging the data that I save to workspace. This functions just fine. The problem is, even with the suppresion ";" on the sim command, my command windown is spammed with a display of a variable, that I have no idea what is, or where it belongs (see fig). This happens while my simulation is running. I am trying to get rid of it - any ideas?

You need to go to your Simulink model to find the source of the assignment line "y=something" where ";" is not present. It could be in a MATLAB Function block, or a Stateflow chart.

Thanks for your reply Fangjun.

My Simulink model is huuuuuge, and I am not sure where to start. It would take hours to find. Is there no way to find the source of it in another manner?

[Fangjun Jiang]

try Ctrl+F to do a blind search for "y =". Good luck!

Alright, so I opened up Model Explorer in Simulink, which gives me a long list of all subsystems and Matlab functions. I looked through each and everyone of them, and all the functions that contain "y = something" has ";" after it. So it cannot be the source. Do you have any other tip?

EDIT: Nevermind. I looked for outputs only, but should have looked at each function block to see if there was an internal variable called y. There happened to be, so I now fixed the problem.

Thanks alot Fangjun!
