Hi all,
I am using Chalmers n- heptane mechanism (http://www.tfd.chalmers.se/~valeri/MECH.html ) for ECN reacting spray validation.
I want to replace the mechanism with T. Lu's n-heptane mechanism (http://www.engr.uconn.edu/~tlu/mechs/mechs.htm). Except the mechanism part, the case setup is the same. The changes are as follows:

1. Replaced therm.dat
2. Replaced mech.dat
3. Renamed C7H16 in liquid.dat to NC7H16 (C7H16 is not available in Lu's mechanism)
4. Defined Parcel as NC7H16
5. Selected fuel as NC7H16 and mass fraction =1
6. In evaporating species selected NC7H16
7. Selected NC7H16 in combustion tab

The simulation is getting initiated. Now the problem is except the species which I initialize (CO2, N2 , H2O and O2) other species are showing zero concentration whereas as in Chalmers mechanism, after the first time step, even though not significant a change in species concentration is observed.

What could be the possible reason? Is it a problem with mechanism ?

Any leads will be highly appreciated
Thank You
