Hello,
This is probably not a functional problem with the model block but perhaps an aesthetical one. When exploring the Multi-Winding Transformer block from the Simscape Specialized Power Systems blockset the block seems to reaaragne the coil configuration in a symbol that renderes the symbol a bit confusing from the top level view. For example for a dual transformer it shows one coil on the left and three on the right. It maintains the symbol even after changing the number of coils and just continues to add ports. Something like this:

Should probably look more like this for whatever its worth:Hello,
