URGENT!! Please look at this models...thanks...

Hi,
I've a problem with the inconsistence of results using lumped port and wave port...
I've attached three models with a doc file relative to both of them.
I've reported the S11 for the three cases.
What causes the difference in results?
Why? And which is the more faithful model between the three?
Apparently I think I've made the same model just using two kind of different ports...what's wrong?The results are totally different:-(
Thanks to everyone who can help me!

please...could anyone help me?
It's very important....
thanks a lot!

Look a number of tetrahedra, the boundaries size and the MAX MAG delta S target

Make sure S11 for each case is normalized to 50 ohms. S-parameters in HFSS are "generalized" meaning they are norrmalized to the computed port impedance.
