surface graph plotting issue

Hi Yun,

Can you share the data file so that I can test?

Thanks,

I attach my postfeko pfs file. if you need original cfx file, let me know and I will attach it

Thank you for sharing the .pfs.

I will need the .ffe along with the .pfs session. Without it the main data is missing.

I tried to upload ffe mile but the system says it is unsupported file format. are there any way to upload data?

You can zip it then upload the zipped archive.

Hi Yun,

I don't see any issue with the plots. Here are some points I have randomly picked from a surface plot of the data. You'll see that all three values were correctly plotted.

Note that the RCS values in the .ffe file are in m^2 and not in dBsm.

If you have specific points where you have observed discrepancies between the data and the plot. Please share their info.

I cheked the .dat file I exported with m^2 surface graph, and confirmed there is no issue in RCS value in .dat file. RCS values are all the same with .ffe file.

but what I thouht wrong was surface graph of dB, not m^2.

could you check RCS value from dB version of surface graph? if you could, export graph to .dat file and see RCS values. mine is:

as you see, there are pointless -4.0 values, which is totally wrong.

this one is showing results converted from m^2 to dBsm.

Hi Yun,

Interestingly, I do not have the same values as you when exporting to .dat:

What version/subversion are you using?

I'm using Altair FEKO 2019.3.3, which is quite old version. 

so far I thouhgt even though I use old version there is no issue, but seems there are bug / software error when converting m^2 value to dBsm.

Indeed, your version is very old. I strongly recommend you update. A lot of enhancements and feature additions have been added since.
