Got Warning...Mass imbalance in reaction stoichiometry
 

Hi there..

Could anybody help me to solve my problem? This is my first time using species transport in Fluent. I'm doing coal combustion involving 2 particle surface reactions.

My first reaction is C + 1/2 O2 CO

2nd rxn is C + CO22CO

I think that my stoichiometry is already balance.. but why I still got that warning..

What should I do?? Pls anybody...really need your help..

Thanks in advance.
