UDF solution variable for time-averaged mass frac?

Hi all,
I'm using a compiled UDF for flux that finds the gradient of species mass fraction for me. The variable the UDF uses for reference is: C_YI or C_YI_RG To reference species mass fraction, though, I would need to have a meaningful steady state solution or instantaneous unsteady solution, and my simulation does not offer that-- it is turbulent [S-A] and highly unsteady. I would like, instead, to reference the time-averaged mass fraction (from unsteady statistics on an unsteady solver). What variable should I reference to get the value of mean mass fraction? Or in other words-- if C_YI and C_YI_RG refer to mass fraction, what would refer to MEAN mass fraction? My thanks in advance, A. S. |
