Hi Ehsan,
I understand that you would like to alter the default settings of the checkbox in the “Three-Phase Fault” Block parameter via code/script.
I would suggest you use “set_param” function in MATLAB for changing the parameter in Simulink. For your specific needs, you can change the parameter as follows:
% Open or create a Simulink model
modelName = 'myModel'; % Replace 'myModel' with your model name
open_system(modelName);
% Get the block path/name
blockName = 'myModel/Three-Phase Fault';
% Set the checkbox on/off
set_param(blockName,'FaultA','off');
get_param(blockName,'FaultA')
save_system(modelName);
For more imformation on “set_param”, you can refer to the following link.
Hope this will resolve your query!
