How to use atmloc?

Dear Fluka experts,
I’ve encountered a problem that’s a bit more difficult to solve when I execute the atmloc executable file.
The questions are :
As you can see in the first screenshot, after I have entered the latitude and longitude, geomagnetic cutoff and other information, why are no files such as .geo .cards generated as mentioned by Professor Angelo in the second screenshot?
And if these files are generated, how do I associate them with my .inp file?
Thank you for your generous answer.

Dear Fluka experts,
I have some problems when I use atmloc.f.
The questions are:
Running the executable file generated by atmloc.f and then entering some latitude and longitude generated atmloc.geo as shown in Figure 1. Afterwards, I put the atmloc.geo file into my .inp file, and the generated geometry (Figure 2) is obviously different from the inp file in /usr/local/fluka/examples/gcr/AllparticleExamples (Figure 3). It seems that there is something wrong with the three cones in the geometry.
My latitude and longitude are similar to those in the example, and I don’t know what the reason is.
And attach my documents. Thank you for your generous answer.

Dear @chenjianqi,

A similar issue has been addressed in the past in this post:Cosmic ray showers - Geometry and Materials - FLUKA User Forum, which I invite you to have a look to. The parameters used in the atmloc have an impact on the construction of the local geometry, particularly of the definition of the cones which constraint the atmospheric layers. Please note that using a geomagnetic cutoff acceptance too high prevents the routine to generate output files (.geo, .sur, etc).

Please note that the example provided with the FLUKA distribution is relative to Tsukuba (36N° 140E°). Using those coordinates in the atmloc produce a very similar geometry to the one provided with FLUKA.

Hope that helps.

Regards,
Angelo
