[FLASH-USERS] Where to compile new programs and modules in FLASH

[Lynn Reid]

Hi Suzanne:

I agree with Nathan that the easiest way to make modifications to a 
setup is to work within the setups/simulation directory -- this is true 
within FLASH2.? or FLASH3.

I would STRONGLY encourage you to work with FLASH3 if you are going to 
make more lasting modifications to a nuclear network -- for example, if 
you want to use your modifications in other simulations. The nuclear 
burning routines have been extensively reorganized in FLASH3 and 
hopefully their layout will be much easier to use. The aprox13 module 
exists in FLASH3 as physics/sourceTerms/Burn/BurnMain/Aprox13. Let us 
know if you want any assistance with the transition from FLASH2.5 to FLASH3.
