How to get 3d field plots from a fully calculated HFSS project?

Hello,

can somebody tell me how to get 3d field plots from a fully calculated hfss project.
The result menu does not provide something ???

Thanks.

you have to select the geometry, and then right click\plotfields\... then you can select the fields you want.

thanks (you got 3 pts)

I have another question.
If I have already calculated modal scattering parameters,
is there a possiblity to get the terminal scattering paramters in post processing.

---

The edges of a waveguide port are set with dependency of the assumed boundary.
If I use radiation boundary on the port face, which boundary is used for the
port edges. PERFECT E ???

Hi,

I think that the modal parameters are the same as the terminal parameters as long as you have only one terminal per port. Otherwise, I do not think you can get the terminal parameters in a simple way

Usually the port edges is assumed as PEC or PMC since in all cases (closed wg, open wg, planar TL, ... ) the fields are concentrated in a certain region and very small around it, so the port edge does not really affect the results much. However, the best way to ensure it, is to use a port of certain size and then increase the size until further increase does not affect Z0 and gamma of the waveguide. However, this is very tedious and time consuming so I do not recommend it unless you really need very high accuracy. Also, take care of the limits of the fabrication and material properties, trying to perfect the model is not always a good idea. Try to make it a simple and efficient for prove of concept, not to get results exactly as measured.

best regards and thanks :)

Hello elektr0,
Have u defined a radiation boundary? If u have, u have to also add the radiation setup to see radiation characteristics of the structure.. Hope this helps.

Why not first try some simulation examples as the tutorial says.
