I am running an analysis of a 3D setup with multiple incident wave sources.
Does anyone know why I don't have the multi-frequencies and broadband options in the analysis setup?
I have an HFSS terminal driven design.
Here is my desktop configuration:
If, for example, I add a lumped port, I am again allowed to use multi-frequiences in the setup.
I don't understand why this option is disabled if I just have incident wave sources.

Thise option is not available when you use Plane wave incidence excitation.
Note that when using Plane wave incidence, there are no S parameters involved and the convergence criteia is based on energy. Also, we cannot use interpolation sweep, but only disceret sweep. If you have a structure which has several resonances, I suggest you create several setup accordingly (for each resonance) and only have a narrow band sweep around the resonance for each setup where you really care about fields. Note that if you save fields for a lot of frequency points in the whole domain, it will slow down the simulations and possibly take a lot of disk space. (depending on your design of course.)
