To Expand Subsystem by using model explorer

Hi,

is it possible any subsystem to expand by using model exploerer?

Thank you in advance

Hi Jiang,

I have a lot of subsystems eacht with an undersubsystem in my model and I would like to expand only the undersubsystems.

It is not to easy click each one individually and expand it.

Because of I would like to carry out with any efforts. For example by using model explorer.

Do you have some other idea?

Thanks.

[Fangjun Jiang]

something like "Expand all" or "Collapse all"?

[Mustafa Uslu]

I wouldn't like to expand the subsystem on the highest level of my model, but each sub-system on the highest level has a sub subsystem.

My goal is to expand all of these sub subsystems, in order to expand without clicking each subsystem individually.

many thanks.

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.

Sounds like a solution!

Hi Sai,

thank you for your solution.

If I try to write below code in Matlab Command window, then I get always this message:

E.g.:

Simulink.BlockDiagram.expandSubsystem('SubsystemExpansionModel/Subsystem')

Invalid Simulink object specifier

Note: subsystems are not masked, linked, or commented.

Thanks

Hi,

Check that model is opened properly and 'Subsystem' is existed inside SubsystemExpansionModel.

If you try to open the subsystem which is already opened, you might get an error.

Hi Sai,

thank you for your tip, it has worked.

I have an additional question to top script, what you did write.

I would like to below 'for loop' for certain paths in my model.

E.g.

for i=11:10:1141    
target= find_system ('modelname/subsystemhighestlevel{i}/subsubsystem');
Simulink.BlockDiagram.expandSubsystem('target','CreateArea','Off');
end

Unfortunately it does not work.

Do you know how a path / directory can be counted up iteratively?

Thanks

Hi Sai,

I have solved this issue with below code script based on your first suggestion.

By the way , it is possible to get child subsystem of subsystem on the highest level with 'SearchDepth'......

Thanks and BR

Mustafa

blocks=find_system('model_name','SearchDepth','2','Name','target_subsystem');
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
