c 
c commands for density & abundances =========
c set the density and composition, ism with grains
hden 10

c
c other commands for details     =========
c this is an important ionization source
cosmic ray background 
c code will stop at 4000 K by default, lower this temp so we
c can do fully molecular gas 
stop temperature 10K linear
