UDS Species calculation is DIFFERENT!
 

Hi All,

I did some modeling with UDS for the species mass fraction because later I want to alter the convective flux part. But, before that I would like to check the validity of this calculation compared to direct species calculation (embedded in Fluent). I found big difference. Has anybody exprienced it before? I also noticed that the diffusvity coefficient in the UDS needs to be multiplied by rho to get the consistent unit.

Thanks.
