MATLAB: Can I save the simout while running parsim after each worker completes its simulation

Can I save the variables to a MAT file while running parsim after each worker completes its simulation?

Best Answer

Yes, it is possible by enabling the "LoggingToFile" and "LoggingFileName" options using the "setModelParameter" parameter.

in = in.setModelParameter('LoggingToFile', 'On', 'LoggingFileName', 'out.mat')

For more information look at the following documentation pages:

https://www.mathworks.com/help/releases/R2020a/simulink/slref/setmodelparameter.html

https://www.mathworks.com/help/releases/R2020a/simulink/gui/log-dataset-data-to-file.html

Please note that the SimulationInput objects and SimulationOutput objects can also be saved separately to a mat file and loaded into the workspace later. You can then use:

openSimulationManager(in, out)

to open the Simulation Manager UI. For more information, refer to:

MATLAB: How to automatically change the dataset logging filename each time I run the simulation

When InitFcn is called, the 'LoggingFileName' value is already set and is thus considered a read-only parameter.

The desired behavior can be accomplished using a wrapper MATLAB script. For example:

for i = ...
    set_param(...);
    sim(model_name); % Programmatically simulate the model
end
