Hello, I am a Feko 2017.1 user. I have a Cartesian surface plot of near field (electric field) (horizontal axis is X, vertical axis is Y, and Z position is fixed). How can I export the data points of this configuration in dat or txt format for post-processing? Please advise. Thanks in advance.

What are the reasons, why the reflected coefficient (Er/Ei) is too law? Can it be because of reflection coefficient is per definition the maximum amlitude of Er devided to maximum amplitude of Ei and my scattered near field at that point is not necessarily equal to the max. Amplitude. (i have drawn it in the picture with Vin and Vref) ------ I calculated only scattered near field. r - reflected, i -incident I have three mediums, the red one in the middle has the eff. permitivity of 18 at GHz, the 2 on the sides the eff. permitivity of 1(air) according to Fresnel Equations r = (n2 - n1) / (n2 + n1) = 0.8947 if i just take my nearfield data at the boundary and divide it with 1V/m incident field, i become r = 0.2

Hi AltairHW I'm using FEKO 14.410 EDU edition and experimenting with the script example https://www.feko.info/support/lua-scripts/radiation-hazard-iso-surfaces/radiation-hazard-iso-surfaces-wizard When running this code I receive an error when setting p1.IsoSurface.Value = 41 "POSTFEKO 14.0.410-277905 (x64) c:\Development\Workspace\win64_Maintenance\utilities\geometry\include\common_RangeOf.hxx (41): Assertion failed: !isEmpty() " If I comment out this line the script completes without error. I can't determine why p1 is failing to set the value. What is strange is p2 is a duplicate of p1 and it will set p2 value without error. p1 = app.Views:Item(views+1).Plots:Add(scaledNearField) p1.Visible = false p1.PlotType = "Iso-surface" p1.Legend.Position = "None" p1.Label = ("RMS_Public" .. append_to_label) p1.Visualisation.Opacity = 40 p2 = p1:Duplicate() p2.Label = ("RMS_Occupational" .. append_to_label) p2.Visualisation.Opacity = 40 -- ERROR OCCURS HERE WHEN SETTING p1's isosurface value -- If I comment out this line the script completes without error -- note that p2 successfully sets the value without error!? p1.IsoSurface.Value = 41 p1.Visible = true -- p2 is a duplicate of p1 -- can set p2 value without error p2.IsoSurface.Value = 92 p2.Visible = true regards David
