Realizability paper accepted

Issue 2261 posted by Dan Swenson of Thunderhead Engineering led to a revamp of the species transport scheme to guarantee realizable mass fractions.  These changes were incorporated into FDS 6.2.0.  The approach we developed has a few novel aspects and so Jason Floyd and I submitted the work for publication in Fire Safety Journal.  Today we got word that the final version has been posted online and may be viewed here.
