Simulink rapid accelerator only returns tout

My model could be compiled succesfully and also the Simulation seemed to run but the only return I got was tout.

My code:

model = 'myModelName';

% build

rapidAccParams = Simulink.BlockDiagram.buildRapidAcceleratorTarget(model);

% Simulation Parameters

paramValStruct.SimulationMode = 'rapid';

paramValStruct.SaveTime = 'on';

paramValStruct.SaveOutput = 'on';

paramValStruct.LoadExternalInput = 'on';

paramValStruct.RapidAcceleratorParameterSets = rapidAccParams;

paramValStruct.RapidAcceleratorUpToDateCheck = 'off';

paramValStruct.ReturnWorkspaceOutputs = 'on';

paramValStruct.RapidAcceleratorUpToDateCheck = 'off';

% run

simOut = sim(model,paramValStruct)

If i run this in 'normal' or 'accel' mode simOut contains both tout and a result struct, but with 'rapid' I only get tout.

Does anybody know what could cause this problem. Any answers would be greatly apreaciated

Hi,

The element 'yout' of the returned object could be just an empty struct as the logging format for the output is set to 'Dataset' by default. Simulation in rapid accelerator mode does not support logging output to a Simulink.SimulationData.Dataset object. You would need to change this to either 'Array','Structure' or 'StructureWithTime' depending on your preference.

Refer the documentation link for further details:
