I would like to use the model construction commands to manipulate the Physical Modeling (SimPowerSystems, SimMechanics, SimHydraulics, etc) connection i/o ports in a manner similar to regular block ports.

The Connection Ports on the blocks are like any other port. The best way to get a handle is to first acquire the handle of the block (use find_system etc.). Once you have the block handle then do the following:

PortH = get_param(blockH,'PortHandles');

PortH will be a structure that will have all the port handles. The Physical Modeling connection port handles will be under the fields LConn and RConn (for left connection and right connection).

When finding a port handle corresponding to a port block, you need to do the following:

1. Search for the peer port blocks (find_system for BlockType PMIOPort with

SearchDepth 1 but not 0)

2. Filter out those with a different Side property

3. Work out the corresponding block number among blocks of matching Side

4. Index into the PortHandles.L/RConn
