So i have a resonator designed in HFSS. I am using the eigenmode analysis on it to get an answer. I then go to DrivenModal once I couple it to a transmission line, to get the scattering matrix. But in order to do this I take the mesh from the eigenmode results and import them into the DrivenModal model.
If I had more than one structure, would it be possible to import the mesh from multiple sources? Or how would I go about doing this?


Any help is appreciated as I am very lost as how to achieve this. Thank You!

The reason I am doing it this way is because the drivenmodal produces a mesh problem which results in non accurate results.

I would probably just set up a seed mesh in the driven modal simulation, rather than trying to import it from an external source. I've found HFSS' mesher to be quite excellent, usually.
I see, so the issue with that is that, the mesh around my structure is very coarse, even with adaptive meshing

the resonant frequency I see, swings around lot

Yes, that is why I would recommend setting up a seed mesh. That way, you can get it as tight as you want in your regions of interest.

I have tried a seed mesh but since its a coplanar waveguide applying a seed to the entire ground plane would result in a very very dense mesh, rather than what i just want which is surrounding only the structure.

Is there any way to go about doing this?

Draw a box (or some other object) where you want your fine mesh. I believe it may be non-model, if not you should make sure it is the right material for its location. Then, apply a seed mesh to this object.

For example, when I'm using CPW, I place a seed mesh in the gaps between conductors.
