How can I creat new result in CST?

[salma]

Hi

How can I creat new result in CST? for example, I want to know subtraction of two results, for example |S11|-|S22|, are there any ways to define this new parameters? in HFSS, I do this using output variables.

Regards

Hi
You can find it in Results>Template Based Processing>Mix 1d results.

dear myazdi83

Thank you very much, but this message is appeared, " No 1d results template exists, Mix 1d not possible".
Do I have to do something before simulation?

 

[myazdi83]

yes.
you should first define your parameters which are contanied in the equation.
for example first define magnitude of S11 from Results>Template Based Processing>s-parameters. Then you should define magnitude of S22. then,You can find it in Results>Template Based Processing>Mix 1d results.

If my results are not exist in the list, for example I need some processing in the E-field of probe, what do I do?

Thank you

 

[myazdi83]

could you write your complete desired equation.

 

[salma]

ok,

A linearly polarized field (E field in the x direction) is incident on my structure.My structure is chiral and it rotates the polarization of the incident wave. I want to calculate the transmission coefficient for the right circular polarized and left circular polarized.So, on the other side of the structure, I measure the transmitted E-field in the x and y direction using probes.
Now, I must calculate Ex+iEy and Ex-iEy. what do you suggest?

regards

 

[myazdi83]

ok.
Have you seen this example of CST?
file:///C:/Program%20Files/CST%20STUDIO%20SUITE%202010/Online%20Help/mergedProjects/Examples_Overview_MWS/examplesoverview/fss__simulation_of_resonator_array.htm
and Is your problem like this?
It would be usefull.

 

[salma]

yes,

My simulation is slightly different. In that example, the incident plane wave angle is varied and effect of its on s_parameter is plotted. But, in my simulation ,the incident plane wave angle is normal and I need to calculate rotation of polarization versus frequency

Anyway, thanks for your help.

 

[myazdi83]

ok.
If you excite the port with only 1 mode (suppose vertically oriented) then the s21(1,2) shows the amount of mode 1 that convert to the horizontal mode. (am i right?)
but if it dont satisfies your desired result, i suggest that export your result data from CST and import them to the MATLAB and do everything you want with them!!!

@ myazdi83
how one can import data to CST from matlab??? do you have any idea
many thanks

i am sorry but i cant find Import Results Curves From ASCII files ????


Many thanks

OK, first create a New Folder and then do it, like this:

@myazdi83
how can we update CST parameter via VBA ? and can run the T-solver with the updated parameters ?

If the defined parameters are global, they will be updated when you define a parameter sweep in T-solver.
Regards.

 

[snowwhite88]

hello
when i asked about importing information to CST i meant that i want to change the parameters from MATLAB ??

 

[ghost90]

If the defined parameters are global, they will be updated when you define a parameter sweep in T-solver.
Regards.

but they are global already ... do you know a VBA code to update the parameters and run T-Solver with the new parameters
i try to start the T-Solver after making parameter sweep by this code
Solver.Start
Save
but it get the result from the old parameters (i.e before parameter sweep)
thank you ..
Regards...

hi everybody
i have a problem with cst output file
when i run my script code with FDsolver(i use floquetprot & unit cell) i got some result like " %SZmax(1),Zmax(1)% versus Passes in dB.tab".
i want link cst & MATLAB then it should be txt file. CST'output should be .sig file to have ASCII outpot then i got error and i cant get outpot in txt file.i should do it with vba code. pleaaaaaaaaaaaase help me its emergency
