Hello people,

I am trying to find fuel fraction distribution in a combustion chamber. I could think of two ways to do this:

1) Do rhoPisoFoam simu,ation and get the converged U field and use this to solve the fuel fraction scalar with scalarTransportFoam.

2) Do reactingFoam simulation with chemistry off.

Now, can anyone tell me whether both of the approaches will give me the same results or not??? Because 1st approach takes much less computational time, so if both the things give same result then 1st would be the obvious choice. But i am confused..Please help

Thank you
