mesh option for memtum

Hey,guys

when i simulate a RF inductor with momentum used in mmic(pic.1)，i have serval questions as follow:

1.generally,how many cells/wavelength should i set in the option of mesh density?if the num is 80,160 200,250,the result varies very differently(pic.2);

2.should i enable the edge mesh and transmission line mesh? the results is also different.the inductor mentalhave beenseted as a 3D-distrubuted thick mental.But in the ADS HELP files,there is "the use of edge mesh is typically not required when the conductors is defined as thick conductors with a 3D-distrubuted model..........enabling the edge mesh for thick conductors will additionally allow to capture the current crowding effect in corners.however that is the secondary effect that in the vast majorityof cases is not required for a sufficient accuracy."it means if your conductor is thick 3d-distrubuted mental,you do not need to enable the edge mesh ,and it will not affect the accuracy seriously.but in my simulation ,it did.(pic.3）；

3.is the set of my port right?

4.there is always some warning (pic.4),what is the problem?

thanks !

Some quick comments:

* The documentation is correct in the assertion that edge mesh is generally not needed if you are using thick metal expansion

* Transmission line mesh is rarely needed

* Mesh density is very application specific. If you have the time, the best approach is to try increasing the mesh density and look for convergence of results.
