How can I connect 3 Simscape ports programmatically

Hello everyone,

Recently I am having a simulink problem:

I would like to connect 3 Simscape Electrical Ports programmatically.

The result should look something like this:

For that I wrote a MATLAB Code that should create the above:

simulink

open_system(new_system('sys'));

% Add Blocks

add_block('nesl_utility/Connection Port','sys/1');

add_block('nesl_utility/Connection Port','sys/2');

add_block('ee_lib/Passive/Capacitor','sys/C');

% Move Blocks

set_param('sys/1','position',[0,0,30,30]);

set_param('sys/C','position',[0,100,30,130]);

set_param('sys/2','position',[0,200,30,230]);

% Find Position

par1 = get_param('sys/1','PortConnectivity');

parC = get_param('sys/C','PortConnectivity');

par2 = get_param('sys/2','PortConnectivity');

pos1 = par1.Position;

posC1 = parC(1).Position;

posC2 = parC(2).Position;

pos2 = par2.Position;

% Connect Blocks

add_line('sys', [pos1;posC1]);

add_line('sys', [pos2;posC2]);

add_line('sys', [pos1;pos2]);

The problem is, that one connection is always missing, and with the above code I get this:

Is there any solution for this?

Hello,

you can directly connect via the port pin names, instead of using the position information:

add_line('sys', '1/RConn1', 'C/LConn1')
add_line('sys', '2/RConn1', 'C/RConn1')
add_line('sys', '1/RConn1', '2/RConn1')
