Transparency issue while adding secondary block

I'm attempting to generate Simscape models using a parfor loop for parallel processing, but this results in a transparency violation error when adding blocks. The error points to the 'PreCopyFcn' callback in the masks of all Simscape blocks. I tried loading the libraries within the parfor loop, but this approach didn’t resolve the issue.

Hi Kamal,

You can use 'parfeval' to avoid the transparency violation error. Here is an example:

1. Define a function to create Simscape model.

function foo(modelName)
    ModelName = modelName; % Set up the model
    proj = new_system(ModelName); % Create a new system
    open_system(ModelName); % Open the new model
    
    % Add blocks
    add_block('simulink/Sinks/Scope', [ModelName '/myScope']);
    add_block('fl_lib/Thermal/Thermal Elements/Thermal Mass', ...
        [ModelName '/myblock'], 'Position', [250 135 300 200]);
    
    % Save the system
    save_system(ModelName);
    close_system(ModelName);
end

2. Call this function using parfeval:

>> f = parfeval(@foo, 0, 'Model_1');

The parfeval function avoids issues related to callbacks and transparency by executing each instance of foo independently in parallel workers.
