Add active scalars for your EGR constituents. Initialize these with the correct mass fraction then track and update them as appropriate.

It depends also on the combustion model used...what are you using?

Dear Ankur
with the EBU Latct model you need to assign specific scalar for the EGR simulation. Thay are:
18 - EGR CO2
19 - EGR H20
20 - EGR N2
Proceed with this metodology: define *set O2 0.23300
*set EO2 0.0
*set EN2 0.13775
*set ECO2 0.03661
*set EH2O 0.01712
and then
iniscalar,18,stan,ECO2,1
iniscalar,19,stan,EH2O,1
iniscalar,20,stan,EN2,1
Regards
