Differents results with solve inside

Hi,

I work on CPW, and I note results differents between experimentation and when I solve with HFSS 10.0 (I use waveport). I get right results between exp and mod only if solve inside is activated for metal of the line. Is it possible to get right results without solve inside be activated with waveports excitations? Thank you.

zaurak.

PS: sorry for my english.
