Hi everyone!

Suppose there are 50 blocks of the same type in a simulink/simscape model - let's say it is a pipe-block in simscape domain.

Is there any recipe to change a specific parameter of all blocks programmatically?

I have a solution, but it assumes that the bocks of the same type are named with a consecutive number like this: pipe_1, pipe_2.

    for iter_pipes = 1:50       
        set_param(...
            model_name + "/pipe_" + string(iter_pipes),...
            "p_I_specify","on",...    
            "p_I_priority","High",...
            "p_I","550000"...
            )
          
    end 

Is there any way to access a specific param of multiple blocks of the same type regardless of the blocks name?

Thank you in advance for any help!

Michael

That´s a good solution. For any other case, you might try to first use the command find_system, to then look for the blocks you want to change.

The following link has some examples of how to use this command:

Thx Jeúsus for the quick response.

Got a second solution, which takes a str. for searchin' specific blocks.

In my case it is more appropriate solution, cause i have to handle with pipenames like pipe_12_a, pipe_12_b....

model_name = "SIM_X";
all_simscape_blocks = find_system(model_name);
simscape_blocks_pipes_idx = startsWith(all_simscape_blocks,"SIM_X/pipe");
simscape_blocks_pipes = all_simscape_blocks(simscape_blocks_pipes_idx);
    for i = 1:length(simscape_blocks_pipes)       
        set_param(...
            simscape_blocks_pipes(i),...
            "p_I_specify","on",...    
            "p_I_priority","High",...
            "p_I","550000"...
            )
          
    end
