Hello,
I created the following udf to calculate the velocity at the outlet(define adjust) and then take that value and apply it to the inlet(define profile). My problem is the define profile seems to run at the same time as define adjust so the define profile is taking the initialized value of 0 and applying it at the inlet. To fix this I added an if statement, the calculated value is inputted into the define profile but now the begin f loop does not loop over the inlet. Any idea what is wrong? Thank you! (Also this is a compiled udf)

DEFINE_ADJUST(vel_calc,fluid)
{
int zone_id = 7;
Thread *outlet = Lookup_Thread(fluid, zone_id);
face_t first;

begin_f_loop(first, outlet)
{
v_out += F_U(first, outlet);
iter = iter + 1.0;
}
end_f_loop(first, outlet)

if (iter > 0.0)
{
v_out = v_out / iter;
v_final = v_out;
printf("Test 0.5=%f\n", v_final);
}

iter = 0;
}

DEFINE_PROFILE(vel_in, here, i)
{
if (v_final > 0.0)
{
face_t second;

printf("\nTest 1= %f \n", v_final);
begin_f_loop(second, here)
{
printf("Test 1.5= %f \n", v_final);
F_PROFILE(second, here, i) = v_final;
}
end_f_loop(second, here)
printf("Test 2= %f \n\n", v_final);
}

}
