Hello,

If I have a port handle in Simulink, I would like to know how to find the port handles of all ports to which this port is connected.

I would also like the solution to work with simscape physical connections.

I know that from a port handle, I can have the handle of the line to which it is connected. But then? If the node is connected to several other blocks, there will be a node on the line, and this makes three lines involved...

I also know about the PortConnectivity parameter of a block, which gives the handle of the destination/source port, but from there, I cannot have the handle of the current port, so I cannot match both...

Thank you for your answers
