[FLASH-USERS] How to put other variables into the output files

[Ryan Farber]

Hi Zhang,

I haven't actually used the conduction sub-unit before but if you do
      grep -in "diff_coeff" *.F90
in the object directory then you should see all the places where diff_coeff
appears. Anywhere where it's value changes (so, something like diff_coeff =
blah) you'll also presumably want to update solnData(DIFF_VAR,i,j,k)
[replace i,j,k with the loop variables if other variable names are used].

Best,
--------
Ryan
