Dear Dr.Craig,
After reading your paper,I tried to build an antenna pattern in lossy heterogeneous environments,but the results remained unchanged.An why only the first of 50 materials is displayed in thhe moel?

Can you print your full input file using the command line flag '--write-processed'
Kind regards,
Craig

I don't see anything fundamentally wrong with your input file. You have specified 50 materials to use with Peplinski soil and fractal box, which you can see listed in the gprMax materials table. Your screenshot from Paraview looks odd, as I don't see the heterogeneous soil displayed there - so perhaps check that as a first step. You are looking at E-plane patterns. I wouldn't have imagined the pattern shape to be quite as smooth given the heterogeneous nature of the soil.
Kind regards,
Craig

Hi~long time no see! Yes,the problem is that there are
50 materials
in the gprMax materials table,but in the paraview is only one.I will try to reinstall gprmax, and then try to run the command again.Thanks for your guidance
Kind regards,
Haoyuan

We discovered a bug with generating fractal distributions that could effect certain specific cases (yours included). It related to the use of float types instead of doubles. This is now fixed, so if you pull the latest version and build/install, you should find your issue is now resolved.
Kind regards,
Craig
