Simulating a Waveguide with CST Microwave Studio

[Filos92 4]

Hey there,

I'm new at this Forum and i hope i opened this Topic in the right Thread, so I am sorry if this is not the case.

I've tried to Simulate different kind of Waveguides (Coplanar, Stripline etc) with CST MICROWAVE STUDIO.

since i changed from version 2015 to 2017 the Simulation won't start anymore.

It give me a Critical Error called: "Adaptive port meshing failed".

The ports are calculated with the port macro for Waveguides.

I hope some can help me.

Thanks in advance,

Greetings,

Filos

,,, Welcome Filos on this forum ... !!
I propose this variant of CPW Stripline, if you do not like, post your transmission line sizes...!!!

[Admin 2545]

These are the sizes that interest you .. ??

 

,, or better, send me  the * cst file

CPW Port

I am very limited with dimensons of the Waveguide.

The inner and outer conductor can be changed but the other sizes are fixed.

It's my goal to simulate first the normal waveguide and than the calibration standards (thru load and short)

But at first I would be realy happy if only the simulation starts

Thank you so much for your help!

Thru Coplanar Waveguide.cst

Send a drawing with them...!!!

should'nt the second port be turned by 180 degrees?

I've tried to setup the Waveguide your way (with my values) but I still got the same error message.

Maybe the CAD model is to small?

Thanks for the offer, but you don't have to do this for me, especially because I still not know how the short has to look like.

See my drawing above, and put the dimensions...!!!

When you act this, CST tells you what is wrong....

It sets the Ports without any problem

I do not believe that...!!!!

[Filos92 4]

the Port was constructed by picked face

[Filos92 4]

did I completly missunderstand something?

[Admin 2545]

[Admin 2545]

,,,use it...

txline.exe

[Filos92 4]

ok... now i got an error called "No point picked for wcs movement to point." 

if i press ok the port will be created. But the simulation stops after the port meshing error

[Filos92 4]

i am unsolveable problem.

the program don't start

i'm searching for a similar type now

[Admin 2545]

,,,rotate or translate the WCS(Working Coordinate System)

[Admin 2545]

[Filos92 4]

Ok i removed the outer conductor ive used the macro again and than i translated and copied the port to create the second one.

But i still get the adaptive port meshing error

[Filos92 4]

ive gote 50.666 Impeadance at the txline tool for this sizes. thats good enough for me

[Filos92 4]

Your totaly right, there might be the problem

[Filos92 4]

what tokens are ment with this?
