Dear experts,
My interest is in simulating the flux and energy spectra of secondary cosmic rays at my geographic location at different altitudes. At the end, interest in mainly in energy spectrum for muons reaching the surface of the earth.
I understand that I have to run routine atmloc.f first. In fluka4-4.0/bin, I find atmlc so I do I run it to generate files to be included in inp? sorry for bothering with such a question but I would highly appreciate your help.
Thank you,
Vincent
Sorry for my previous question.
I managed to run the routine but I do not see the expected files being generated.
Am I missing something? I attach part of what I see on the terminal. Note that I entered arbitrary parameters
Dear @Motlatsi_Vincent ,
Many thanks for your question. Could please elaborate more on the issue you are encountering? It is still related to running the atmloc?
Many thanks,
Angelo
Thank you @ainfanti for your response.
I did manage to run atmloc routine.
I wanted to create local atmosphere geometry for my latitude and longitude. I also want to incorporate altitude, which I will later on vary.
However, I am not sure if my input requested after running atmloc is correct. Please assist me. Here is what my input.
Geographic or geomagnetic coordinates;
-33, 18
(I understand that this is geographic latitude and longitude)
Geomagnetic cut-off accentance (GeV);
10
Topmost altitude for particle tracking (said to be above 0.644969E+09) as 0.645E+09.
Question:
How do I include the altitude at which I want to calculate particle energy spectra? Say my altitude is 600 m above the sea level.
Thank you
Dear @ainfanti and other experts,
I managed to generate a local geometry file and the associated files using atmloc.f routine by selecting geographic coordinates (geographic latitude= -33, geographic longitude = 18, altitude = 0, geomagnetic cut-off acceptance = 1 and topmost altitude = 1e10).
I renamed other files appropriately following an example.
I am aware that there are some errors in my geometry and everything looks strange to me because I only used the files generated by the routine. I am not sure how I should rectify this.
Could you please help me understand what the cause of this is and how I should rectify it?
I would really appreciate your assistance.
Here I attach my input and accompanying files.

Thank you in advance
Dear @ainfanti
I kept on making my effort on trying to figure out what the problem is with my input file related to cosmic ray shower simulation and I still don’t understand why I get geometry errors even after going through all topics on cosmic ray shower simulation in the forum.
Seemingly, my problem is similar to this, whose solution was suggested by @horvathd but nothing works out to solve my challenge.
Why is flair not recognizing my cards even when I followed appropriate procedure to generate everything?
I attach my files for checking.
Thank you

As indicated by Flair, there is an error in the definition of the EarBLK region contained in the atmloc.geo file:
* Earth black hole:
EarBLK -5 + -cutcone2
where a body name is missing after the + sign.
