How can I initalize bus objects with parsim in rapid acc mode?

Hello,

I want to run a Simulink model with busses with parsim in rapid accelerator mode. However, I get the error message 'The rtp structure passed in did not have a parameter bus_object'. It works if I execute the simulation in rapid accelerator mode with 'sim' only but not with 'parsim'. I attached a simple example file that produces the error. I am using version 2018b. Thanks for your help!

Best,

Sebastian

Hi Sebastian,

bus_object is not a variable used in the model and thus when the model is compiled for rapid accelerator, it does not appear as a rtp parameter which gives the error. Just remove the setVariable call for bus_object and it should work fine.

for i = 1 : length(final_value_sweep)
    simin(i) = Simulink.SimulationInput(model);
    simin(i) = simin(i).setModelParameter('SimulationMode', 'rapid-accelerator',...
        'RapidAcceleratorUpToDateCheck', 'off'); 
    simin(i) = simin(i).setVariable('final_value',final_value_sweep(i)); % sweep
end

Simulink.BlockDiagram.buildRapidAcceleratorTarget(model); 
out = parsim(simin, 'ShowProgress', 'on');

If you need base workspace variables assigned to the workers, you can set 'TransferBaseWorkspaceVariables', 'on' with parsim.
