Hi,
is it possible any subsystem to expand by using model exploerer?
Thank you in advance

Hi,
One possible idea is to use Simulink.BlockDiagram.expandSubsystem(subsys).
Step-1: Get all the blocks and subsystems in the model using find_system(modelname,'Type','Block')
Step-2: Apply Simulink.BlockDiagram.expandSubsystem(blockname). This type of Subsystem expansion applies to the currently selected subsystem level. Simulink does not expand other subsystems in a nested subsystem hierarchy which is the functionality you are looking for.
Example:
blocks = find_system(model_name,'Type','Block');
for i = 1:numel(blocks)
    try
        Simulink.BlockDiagram.expandSubsystem(blocks{i})
    catch
        %This will catch when we try to expand anything apart from Subsystem.
        continue
    end
end
Hope it helps.
