[Flash-X-users] Getting Flash-X to work

[kiyarash Taghiniyarami]

Dear Peter,
Following are the steps I have gone through and hope it will help you:
1-The CCSN is a really diverse issue consisting of
Radiation+Hydro+Grivity+EOS+Nuclear+etc physics.
To focus on the FlashX you can run just core collapse before the bounce in
1D then extend it to 2D (source/Simulation/SimulationMain/CCSN_WL).
working on it and extending it to 2D with weaklib would help you a lot to
understand how Flashx works (without neutrinos).
2-For the radiation part try to read the https://urldefense.us/v3/__https://arxiv.org/abs/2102.02186__;!!G_uCfscf7eWS!b089MiYCR5YM0PYzTWI7F4EXyszI-z90J5N0B-rsbBz5aMxt87VCa5YtzTPr0Q-Qu-MooOgQ0CcnoT2X5S7MErPX18CTQGqutUKwFn4o$ 
and https://urldefense.us/v3/__https://trace.tennessee.edu/utk_graddiss/7742/__;!!G_uCfscf7eWS!b089MiYCR5YM0PYzTWI7F4EXyszI-z90J5N0B-rsbBz5aMxt87VCa5YtzTPr0Q-Qu-MooOgQ0CcnoT2X5S7MErPX18CTQGqutSEMwwHO$  and you can watch the
series of https://urldefense.us/v3/__https://www.youtube.com/watch?v=tK1HbAiCPuw__;!!G_uCfscf7eWS!b089MiYCR5YM0PYzTWI7F4EXyszI-z90J5N0B-rsbBz5aMxt87VCa5YtzTPr0Q-Qu-MooOgQ0CcnoT2X5S7MErPX18CTQGqutT2tS7iT$   for introduction of
DG method and then download thornado (https://urldefense.us/v3/__https://github.com/endeve/thornado__;!!G_uCfscf7eWS!b089MiYCR5YM0PYzTWI7F4EXyszI-z90J5N0B-rsbBz5aMxt87VCa5YtzTPr0Q-Qu-MooOgQ0CcnoT2X5S7MErPX18CTQGqutSZl6Ofh$ )
and get deep into it (I mean check its all subdirectories out to understand
how it works) and run the tests (such as sine wave streaming, damping,
diffusion)
3- After that you can run the test of sine streaming, doppler shift,
relaxation and deleptonization wave test in Flashx
4- Then you can start the run of
/source/Simulation/SimulationMain/CCSN_WL_Transport
......
There lots of detail in each step you have to take for example digging into
weaklib eos and hybrid eos and understanding of nuclear burning (
https://urldefense.us/v3/__https://arxiv.org/abs/astro-ph/0509698__;!!G_uCfscf7eWS!b089MiYCR5YM0PYzTWI7F4EXyszI-z90J5N0B-rsbBz5aMxt87VCa5YtzTPr0Q-Qu-MooOgQ0CcnoT2X5S7MErPX18CTQGqutZSKvh86$ ).
Btw for compilation and setup errors and making true makfile.h you have to
get help from someone in your university which knows the cluster(you work
with) well.

This topic you are working on is full of frustration. Do not get
disappointed.
P.S. Do not forget to use FlashX github, especially its commits and
branches which could take you to earlier development of the code stages
with the collaborators comments which are truly helpful.


Kind Regards,
Kiya
