[FLASH-USERS] adding subroutines

[Ryan Farber]

Hi Maksim,

Many thanks, Ryan! Can I ask a couple more questions, please? I took one of

Sorry, I don't think I understand the question (and I looked at the
screenshot). It shouldn't matter what the files are named. So you should be
fine but maybe I'm simply not aware of your concern.

Also I am trying to implement tabulated EoS. It works just fine but I need

*(make -j 4 | tee compile_stdout.txt) 3>&1 1>&2 2>&3 | tee
compile_stderr.log*


*cp ${FLASH_PATH}/$OBJECT_PATH/{flash{4,.par},amr_runtime_parameters}
${RUN_PATH}cp ${SCRIPTS_PATH}/{clean_run_dir,m-00.cie,run_basher.bash}
${RUN_PATH}*

Best,
Ryan
