Hi,
I understand that you are receiving error while simulating simulink model using for loop and sim(model).
The error message suggests that the model simulation has encountered a singularity, which may be caused by dividing by zero or approaching an infinite value in any one of the blocks.
It's possible that when you include the `sim` command within the loop, the simulation may be progressing too quickly and not allowing enough time for the model to stabilize before the next iteration. This might result in the model diverging from the expected behaviour and causing the singularity.
One of the possible workarounds could be:
To add a pause within the loop to allow enough time for the model to stabilize before the next iteration. You can adjust the duration of the pause as needed to ensure that the model has enough time to reach a steady state before the next iteration begins.
Here's an example code that includes a pause of 1 second between model simulations in a for loop:
for i = 1:n
% Prepare input signals and set parameter values
...
% Simulate the model
simOut = sim(model);
% Process simulation results
...
pause(1); % adding 1 second pause before next iteration
end
You might also try reducing the simulation step size or tightening the error tolerances by adjusting the simulation parameters. This helps to identify the source of the singularity and mitigate its effects.
