I tried more thinks in HFSS, includying a coaxial waveguide, adding balls to connect the wires..., and I´ve also tried CST creating the helix with unidimensional wires. In CST I got good results in the middle of the simultation, but at the end of that, when the transient in completed there are...
Hi,
I want to create a wire like an helix in CST. Do you know how to do it?. I can create an helix now, but not a wire (and wires accepts simplifications).
Hi katko,
I followed your advices. I´ve set the convergetion condition to 3 converged passes, and I tried higher frequencies and a smaller mesh, but the results are not valid.
Do you think there is something wrong with the placement of the wave port?
I really appreciate your help. I´ve uploaded my last model.
If the varialble "Wire_Turns" is set to 16, the result should be the attached in the image. This is the real S11 parameter of the prototype. As you can see, the results are absolutely differents.
With less than 4-6 loops...
HFSS never again
I don´t know where the problem is. I´ve a model fast to simulate (5 minutes), it converges in a few iterations and it´s very simple to understand and draw.
I´ve built it in the reality and calculated the radiation peaks.
Right now, everything sounds good, but the results vary...
Hi guys,
I have a problem with a simulation. The solution converges succesfully, but the results are not the waited. If I use a really low convergence condition, I get good results (not always).
Have you ever seen that problem? I think maybe there is something wrong in the model, and it...
Hello,
I want to limit the complexity of mesh used in my simulation, because it´s too high (about 200k-300k). I can do it defining a mesh operation and aplying it, but when the simulation starts this limit is not respected.
Doy you know how to limit it?
I tried using PML to decrease the...
Hello experts,
I want to simulate the radiation of a loop excitated by an induced current. I mean, there is current around the loop with a given frequency, and the loop should radiate consecuently.
I tried to simulate this problem with a "driven modal" solution, but I got no logical results...
Hello All,
I´ve designed an inductor antenna, and I want to get the radiation pattern between 0.5 and 1.5 GHz.
My results at HFSS does not fit with the real mesurements. Can you review my project and tell me where is the error?
I´ve lost some days with that project learning with the...
solution type
Hi to all,
I have readed that in the user guide:
1. Driven Modal - calculates the modal-based S-parameters. The S-matrix
solutions will be expressed in terms of the incident and reflected powers of
waveguide modes.
2. Driven Terminal - calculates the terminal-based S-parameters...
Hello guys,
I´m new with HFSS. I´ve done an antenna, and build it physically, so I could compare the results of HFSS with the results of my network analyzer.
The results are not similar. With the network analyzer I can measure the gain in dB at any frequency in a range, and I get a peak around...
