Tushar_Telmasre is on a distinguished road

I am trying to solve for solidification in simple binary systems with convection and Species transport. At the end I want to plot species fraction in terms of C_mix(mixture concentration) which is defined as



fl=Liquid fraction
Cl= Liquid concentration
del_f = Difference in liquid fraction in successive time steps.
k= Partition Coefficient
C0= Alloy Composition
C_old = acts as counter (initialized as C_old=K*C0)

I am trying to write the UDF but do not know where to hook up the UDF in species model.

Here is my UDF

#include "udf.h"

real c_m,k=0.3,c_new,c_old=k*0.1;
c_m=C_LIQF(c,t)*C_YI(c,t,i)+c_new ;
return c_m;
