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?

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

simin = setModelParameter(simin,'LoggingToFile', 'on', 'LoggingFileName', 'out.mat')

For more information, refer to the following documentation pages:

https://www.mathworks.com/help/releases/R2024a/simulink/slref/simulink.simulationinput.setmodelparameter.html

https://www.mathworks.com/help/releases/R2024a/simulink/gui/logdatasetdatatofile.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 GUI. For more information, refer to:

The provided answer is incorrect. In the first line of provided code, the parameter 'LoggingToFile' must be set to 'on'. This parameter is case sensitive. Using 'On', as shown, does not work. A similar issue is documented in this question: https://www.mathworks.com/matlabcentral/answers/2011292-saving-signals-for-each-case-of-parsim-simulation

[Note: Mathworks appears to have corrected the line today.]
