UDF for Outlet
I want to get average concentraions at the reactor exit using UDF..
But there is no options for Hooking UDF in outlet BC..
How to do this..
This Avg. exit conc will be used in specifying the Inlet conc..as it is a recycle process... C_in=f(C_exit, time)
Thanks in advance..

Re: UDF for Outlet
Dear Karthick, Thanks for ur suggestion.. I read the documentation, but could not get how exactly I had to use the Define_Adjust or Define_execute_at_end Please try if you can give me some more hint over following case..
I am modeling a reactor followed by recycle tank.
It is a batch process..
/* C_in = C_exit + C_initial * exp (-t/Th) */
/* This is my Function for three species present in the system.. */
I had written foll. UDF to modify the Inlet BC,.. but i am not able to get the exit conc for the three species.
DEFINE_PROFILE(unstd_cod, thread, position)
float t, conc;
t = RP_Get_Real("flow-time");
conc =C_exit + C_initial*exp(-t/Th);
F_PROFILE(f, thread, position) = conc;
