How Can I create Hollow Rectangular plane - Cartesian system for Near Field Plane?

Note: I don't want to split them in 4 rectangular pieces..

a) averaging of contour miss the trend - Single plane Vs Split planes.  Points Spacing maintained same or good match

b)  Is there a way to add more than 4 legends

    This can be done but only from EDITFEKO.

     

    Create any near field request in CADFEKO.

    Save the CADFEKO model.

    Go to Solve/Run -> EDITFEKO.

    Click YES when prompted like below.

    EDITFEKO will open with an ASCII text (*.pre) file.

    Scroll down to the line that starts with FE. 

    Put the cursor there and hit F1 to edit this line (the near field request).

    Use the 'Specified points' option. In the below I have 4 arbitrary points.

    To view the requested points in POSTFEKO, run Solve/Run -> PREFEKO.

    Then run POSTFEKO to view the final edited model.

    Click Nearfield in POSTFEKO and it will show yellow dots where the requested near field points are.

    Then run FEKO to solve.

     

    The solved near field will be displayed in POSTFEKO as colored dots only, according to the legend, but there will be  no interpolation/smoothing between points.

    Thanks, I will try for Legend (Single Vs Splitted). This option can be used for HPC job too by editing pre file ?

     

    Hollow rectangular Near field ? any comments

    For HPC too, yes.

     

    In terms of using a single plane (not split), try increasing the number of near field points. The near field samples seems rather coarsely spaced.

     

    In general also near field samples should have a small spacing to the nearest surfaces, usually similar to the triangle edge length on the surface.
