species mass fraction unbalanced
 

Hi,
I'm trying to run a volumetric reaction model in Fluent 6.0. To be sure that I've set up the model correctly, I put the mass fraction of one of the species at inelt = 0 and turn off the reaction (which means I'll have the mass fraction of the other species (the only one in the whole simulation now) to be one. However, I get this mass fraction to be much different from one ( range is 1 - 0.08 etc.)
Can somebody please help me out?
Thanks
Ashish
