Hello,

I am trying to find for all the Divide blocks in a model subsystem (and its children) but with no success. Here is the code that I use

Global_path = 'MyModel/MySubsystem';
blks = find_system(Global_path,'BlockType','Divide');

but with no success. On the other hand, as I think that Divide block is basically a Product block, I use this syntax instead:

Global_path = 'MyModel/MySubsystem';  
blks = find_system(Global_path,'BlockType','Product','Inputs', '*/');

The latter code seems to work a bit better. However, I have two questions:

1. Are we sure that I am searching only in 'MyModel/MySubsystem'? I DON'T want to search in any other submodel, i.e. 'MyModel/AnotherSubsystem' shall be exluded

2. This method is not very robust as it search only blocks that has exactly '*/' as input. If I have a block that instead would have '**/' will be excluded. How can I robustify my code? For example by searching for all the blocks that CONTAIN the string '/'?

Many thanks!
