MATLAB: Prevent update simulink diagram

simulink diagram update

How to perform a batch of simulink diagram simulations while preventing the diagram being updated each time?

Best Answer

As long as you're not making structural changes to the model or changing non-tunable parameters (i.e., changes that require the model to update), the update process should be a lot quicker.

Maybe it would help to know what kinds of modifications the script is making, and we can see if there's a more efficient way to get around this?

MATLAB: How to tune parameters in rapid accelerator mode without rebuilding the model in Simulink 7.9 (R2012a)

In order to tune parameters in rapid accelerator mode without rebuilding the model in Simulink 7.9 (R2012a), perform the following steps:

1. Open the modified Van Der Pol demo model('vdp_tunable.mdl') attached below and collect the run-time parameters in a run-time parameter structure while building a rapid accelerator target executable using the Simulink.BlockDiagram.buildRapidAcceleratorTarget function.

open_system('vdp_tunable')
rtp = Simulink.BlockDiagram.buildRapidAcceleratorTarget(bdroot);

Before building the rapid accelerator target in Step 1, you also need to perform an additional step of enabling the "Inline Parameters" option which is required for Rapid Accelerator parameter tuning and then adding the tunable parameters from the list to the "Global(Tunable) Parameters" table. This has already been performed for this model as can be seen from navigating to Configuration Parameters -> Optimization->Signals and Parameters ->Inline Parameters->Configure.

2. Tune the parameters by modifying the parameter structure by using the Simulink.BlockDiagram.modifyTunableParameters function.

rtp  = Simulink.BlockDiagram.modifyTunableParameters(rtp,'a',10);

3. Specify the modified parameters to the SIM command by using the RapidAcceleratorParameterSets and RapidAcceleratorUpToDateCheck parameters as follows:

sim(bdroot,'SimulationMode', 'rapid','RapidAcceleratorUpToDateCheck',..'off','RapidAcceleratorParameterSets',rtp);

The model simulates with the modified parameter without rebuilding.

MATLAB: How to initalize bus objects with parsim in rapid acc mode

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.
