Stacked dielectric materials setup in HFSS

Hello,

What is the proper way of simulating two parallel plates filled with 2 different dielectric materials stacked one over the other in HFSS? the results I'm observing my my simulations seem to suggest that the simulator assumes the boundary between the 2 dielectrics to be a perf-E and thus, doesn't consider the dielectric above the boundary. Please someone provide clarifications here. Thanks in advance.

Hi,
HFSs will apply a perfect E bounday condition to all external surfaces of a model

To be sure about the real BC applied to a certain model you must verify the BC before to start the simulation.

I would bet that
the BC in your model are different to what you believe.
In any case the surface between two dielectric is correctly handled by HFSS with no problem...

Hope this helps
