[FLASH-USERS] flash-users Digest, Vol 108, Issue 7

[Slavin, Jonathan]

Hi Michiel,

I have used the SutherlandDopita formulation of optically thin radiative
cooling with FLASH 4.3 and it does work.  I don't recall off the top of my
head if I needed to do anything special to make it work.  You do need to
get the cooling function data files, though a little googling will get you
to Ralph Sutherland's site where they can be downloaded.  And you'll have
to supply certain parameters in your flash.par including the path to the
data file (as cool_fctn_file) and useCool = .true.  Also you'll need to
supply the correct switch to setup:
-unit=physics/sourceTerms/Cool/CoolMain/SutherlandDopita
I think that's all.  If you run into trouble, ask me and I'll try to help.

Regards,
Jon
