Hi Vijay,

Here the information you asked:

• I use Finit Rate / No TCI with the Explicit source for chemistry solver.
• Density formulation in the initial case is ideal gas 
• Rate exposure is equal to 1 
• The initial time step in the plot were 10e-5 which corresponds to the Chemkin methodology, but I noticed the same behavior with lower time step like 10e-7. I quick run a case with 10e-8 same result.
• Scheme used is Coupled, however I ran the same case with SIMPLEC and PISO and obtained even higher value of mass

 

I put the screenshots for the differents menu

Perhaps, it might be usefull if I share the model or the setting file with you.

Regards,

Ghislain
