Hi all,

I am solving solidification problem in binary systems. I am solving continuity, momentum, energy and species equation.

At the end of calculation, I intend to plot contours of new variable C_mix which is defined as

C_mix={f_l*C_l+integration(C_s*df_s)from limits (0 to f_s)}

where,
f_l=Liquid Fraction
C_l=fraction of solute in liquid
C_s=fraction of solute in liquid
k= partition coefficient
also,
C_s=k*C_l
f_s=1-f_l

Can anyone tell where I can define the new variable? I am prepared to write a UDF, But where to plug that UDF to get desired contours?

Thanking in anticipation.
