default cosmic ray simulation created based on 'japan. I want to specify it for Colombo Sri Lanka. How do I Do that? What are the changes should i do?
Dear @as2020250,
You can refer to Chapter 16 of the FLUKA manual (see in particular section “16.3.2. Local atmosphere model”). In essence, you have to use the atmloc.f
routine provided with the FLUKA distribution. The routine will ask you to provide several parameters (e.g. geomagnetic or geographic coordinates of the region of interest, momentum cutoff, etc): of course, these parameters depends from your specific case study.
Please note also that the topic has been addressed in several other posts in this forum: I highly encourage you to have a look to already published posts.
Regards,
Angelo
