Dear All,

I have a little problem in trying to get S11 of a multilayer model using HFSS. The multilayer model needs to be simulated so as to be infinite in extent so on its sides a pair of master-slave boundaries are added and at the bottom a PML is added to absorb radiation while at top a wave port to make S11 simulation...

After that when I try to simulate it is said that I have an error of having touching between the master-slave boundaries and the wave port boundaries...

The problem is that I have to model the 4 lateral sides with PML boundaries and the top with a port and the port must touch with the lateral sides at the edge...How can this be solved?
