HFSS says my lumped port is only touching one conductor

[Ente]

Hello, i am trying to simulate a microstrip coupling in HFSS. I am coupling 2 mikrostrip lines with an apperture in the middle but when i ym trying to simulate it it shows me this error message:

'1' conductors touch lumped port '1', typically a lumped port contains 2 conductors.

Here you can see my entire Model. the lumped prot is red circled.

when i turn off everything else you can see it better. the lumped port is connected to the upper perfect e sheet and the bottom groundplane ( a perfect e sheet as well). Is the Problem here that the microstripline is basically just a sheet on the dielectric material? should i consider thicken it to make it more like a conductor? the microstripline is as an sheet exactly on the 1st layer and the second layer is placed on it without any space in HFSS could this be a problem?


otherwise i dont know where i should search for my misstake. Maybe you guys can help me!

Using sheets as conductors and attaching ports can cause problems like this. Expand your sheets into finite-thickness volumes, make sure the port overlaps the thickness, and see if that helps.
