I am trying to run a batch simulation in MATLAB using the following code:

in(i) = Simulink.SimulationInput(model);
in(i) = in(i).setPreSimFcn(@(x) myInitFun());     
        
in(i) = in(i).setModelParameter(...
    'LoggingToFile', logFileFlag,...
    'SignalLogging', signalLogging,...
    'LoggingFileName',logFilePathName,...
    'StopTime', num2str(stop_time.sim_end),...
    'SaveFormat', 'Dataset',...
    'SaveTime', 'off',...
    'SaveState', 'off',...
    'SaveOutput', 'off',...
    'SaveFinalState', 'off',...
    'DSMLogging', 'off',...
    'ReturnWorkspaceOutputs', 'on',... 
    'Profile', 'off',...
    'InspectSignalLogs', 'off',...
    'DatasetSignalFormat', 'timeseries'...
    );
simJob = batchsim(myCluster, in, ...
    'Pool', wn,...
    'AutoAddClientPath', false,...
    'AutoAttachFiles', false,...
    'ManageDependencies', 'off',...
    'AttachedFiles',filesToAttach,...
    'TransferBaseWorkspaceVariables', 'off',...
    'CleanupFcn', @Simulink.sdi.clear);

I've configured logging to save some signals from the Simulink model, but I'm facing an issue. Instead of saving the log file in the server directory specified by logFilePathName, each worker saves the log.mat file to its temporary folder. Only after all workers are done does it move the log to the correct folder. This has caused the cluster machine to run out of disk space.

What can I do to avoid this issue and make sure the log files are saved directly to the specified server folder to prevent disk space problems on the workers?
