Simulating a Waveguide with CST Microwave Studio

[Admin 2545]

Tokens currently available  it must to be #0

I think you need to install the CST Studio again

[Filos92 4]

i will do so, but that will take a wile.

i'll get back after doing so.

Thanks for everything!

I don't understand this.

I reinstalled CST and build up a totaly new microstrip in standard geometry. Runned a simulation and it WORKED!

Then i saved it and added more and more copper to the sides to the top and so on. After every copper plate i runned a Simulation to test the new Setting.

After adding the last one I've got the old error message "Adaptiv Port Meshing faild".

I was shocked and had done it undone... but the error was still there.

I opend the first microstrip which has worked , resimulated it and i've got the error message also.

Maybe i should reinstall the old version

Change the frequency of simulation

[Filos92 4]

i simulate all the time from 0 to 20 GHz . Thats the Frequenzy I'm interested in and its worked before, why should I change it?

[Admin 2545]

Is too big bandwidth, can not cover ... !!!

Give me cst * file in the old version

[Admin 2545]

Try something like that

[Filos92 4]

This thing worked before. With results (S21, S11) similar to an existing measurement. Now I got the same array as ever

Thru.cst

[Admin 2545]

*cst.file  the old version

[Filos92 4]

what do you mean?

[Admin 2545]

cst2013

[Filos92 4]

i dont see any option to do this. i google this wait a second

 

[Filos92 4]

CST should be apble to open this

Test.nas

[Filos92 4]

OH MY DEAR,

I found the problem :D:D:D

I have no idea why this happend but CST is creating a working file folder and has no rights to write in this folder! After changing the Rights manually it worked!!

beacause it can not overwrite the old files it says not possible to calculate.

I'm so happy

And thank you thousend times for your help!

I really think thats a problem of the 2017 Version,

I will write the support

[Admin 2545]

,,,from where did you get cst2017...??

[Filos92 4]

Its a original educational licence why?

I think from the main Website

Philos, and this Waveguide with CST Microwave Studio ,is for a school project...???

[Filos92 4]

No, Our University Working Group is using a (little more complex) waveguide as a sampleholder to investigate dielectric properties.

And i want to substantiate our measurements with simulations

[Admin 2545]

Well, then try to do a simulation at this....

[Filos92 4]

why should i do this? as I said before i'm very limited in my dimensions. 12L x 10B is already the maximum we can use

[Filos92 4]

or do you think the dimensions in your drawing (29x8) are not relevant?

If not is the parabolic curvature relevant?

what can i expect for S11 and S21 in this setting?

We are still looking for an ideal design, so i'm really interested in.

[Admin 2545]

,,,or so...

Filos, are you a professor or assistant at the university?

[Filos92 4]

ok i will try it

i'm really exited.

do you have same papers for the properties of this waveguide?
