Hello all, 

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. 

Thank you!

Hi Tomas,

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.)
