cst current distribution

anyone know how to setting the current distribution file in the cst
beside that how to see the RSD file to see the current distribution?


regards,
kyg
 

cst to current gmt -5

use the "field monitor" and select H-field/surface current at the frequency you want to see the current distribution. After the simulation, you find the current distribution in 2-D results in the left column.
 

maximum surface current frequency cst

it is same when we see the result for the surface current and current distribution?
i see that at Solve - Current Distribution can be setting and need to browse the RSD file.

Click to expand...

what do you mean by current distribution then?
 

see what distribution

i saw at cst setting can add current distribution
so i am confusing about surface current and current distribution

how to see current distro

hi shameemkabir

do you know how can we get surface current for the range of simulation frequency?

just like we normally get S parameters from minimum to maximum frequency

regards

you have to define the frequency where you want to get the surface current. it is done with "field monitor" and select H-field/surface current and change the frequency of your interest. Please press apply button for each frequency in the field monitor.
 

check current distribution on cst

hello shameemkabir

well thanks for your reply but i think you havent read my question carefully.
i know how to define frequency monitor for surface current/H field or any other farfield parameter in cst

to make it simple my question was how can i plot a graph in which frequency is along x axis as in S paramter plots but surface current in mA or A along y axis and not Sxy as in S parameter plots

i hope now you understand what i want

thanks anyway
 

export surface currents from cst

Hello shahid.. Have you figured out the solution of your question? you succeded in plotting a graph for current distributions??
 

surface current plot in cst

hi there

well still looking for success.


regards
 

hi all,

from the simulation cst, surface current monitor result, what can i do in order to tune the antenna?
how to understand the surface current because if i can understand that result i can optimize the antenna

regards,
kyg
 

About the discussion, Looking the Surface current and then exporting the data into a text file
file -> export->Plot Data (ASCII)... and the using Matlab importing the txt file (this file contains the coordinates X,Y,Z and in each point the value of the current Ix, Iy, Iz) is quite easy to plot it.
 

hello, can anypne help me to get countour-like current distribution in cst? I had monitor the H- surface current. the option that i was given only arrow, cone and hedgehog. how can i get some plot like the attachment? thanks a lot.

Hello,

When looking at the surface current monitor you first of all should choose one of the given results for example the "Abs".There you can choose a view thats called contour. It shows you a result like in your attechment. If you want to see the distribution in a special plane, you have to do a right-click and then choose 3D Fields on 2D Plane. Then choose the Plane you want to see.
