solution setup hfss

hi, ansoft guies:

There is one simple question about HFSS.

Since Adaptive 'Single frequency' analysis will allow users to setup 'Requested Passes', what number will be suitable? I used 7.

However, issues come up! The results,obtained by 'Single Frequency', differs greatly from 'Sweep' analysis

results? Because of the higher accuracy of 'Single frequency' analysis, I prefer it than sweep one. (Actually,sweep results is the Pass 1 results on Single Frequency analysis.)

Then, what value does 'sweep' analysis have with so poor accuracy, whose mesh will not be refined. In another way, in which way should we treat the data from 'sweep analysis'?

Sincerely,

If you first do the convergence analysis for a single frequency, the mesh used in the final pass is recorded.
There is an option for the mesh used in the frequency sweeping. Choose "current mesh"(?), then the sweep will be done with the mesh recorded above.
