I have another irrelevant question. In the “ (radioactive) isotope” part and “ Heavy ion:”, some examples are different. It lacks a few lines of code. I want to know what the functions of these lines of code are and whether they can be omitted
The slides refer to a new version of the source routine format “source_newgen.f”, which has been simplified to make it more user friendly, while your snapshots refer to the old source routine format “source.f”, which is still working but a bit less user friendly.
The new format is based on Fortran90, therefore its variables have longer and more evocative names. Additionally, a lot of lines that do not have to be touched by users have been moved into library subroutines.
I advise you to work with the new “source_newgen.f”, you will find it simpler and more convenient.
