good idea... btw, how do we re-use meshes/solutions from other analysis setups? is there a setting for that? i never tried that...rfmw said:What I'd do in your case is to start the simulation at the lowest solution frequency (4GHz in your case), then add a 5GHz solution frequency which uses the mesh from the converged 4GHz solution, then add a 6GHz which uses the converged mesh from the 5GHz and so on.
Then I add a broadband (4-6,5GHz) frequency sweep to the last solution frequency (6,5GHz in your case).
I would expect that the mesh is good at every solution freq, so broadband sweep (discrete of course) would give good results.
peleda said:When you use fast frequency sweep, the meshing is done at the solution frequency, and an extrapolation is done. Hence, you would want your solution frequency to be in the middle of your band of interest.
Now if your antenna has multiple resonances, then you may have to shy away from using fast frequency sweep.
When you do discrete sweep, the meshing is done only once at the solution frequency, and the remaining frequencies are solved based on the solution frequency mesh. Hence, for discrete sweep, it is advisable to you put the maximum frequency as the solution frequency.
