UDF Interpretation Error
 

Hi, I am trying to impose a time-dependent boundary condition on a face with a UDF. I am using a monitor to verify that my input function is being read properly and I see that Fluent is interpreting a function other than the one that I am inputting. My UDF is as follows:

#include "udf.h"
DEFINE_PROFILE(unsteady_pressure, thread, position)
{
face_t f;
real t = CURRENT_TIME;
begin_f_loop(f, thread)
{
F_PROFILE(f, thread, position) = (912199393440*t)*t + (1260098450)*t;
}
end_f_loop(f, thread)
}

The problem is that Fluent is reading the above function and reading back the following function with an area-weighted average monitor:
p = 2348190783*t*t + 1259645132*t

Notice that the linear term is interpreted properly but the squared term is not. I have also verified that this is not an issue with choosing to use an area-weighted average monitor instead of something else like an integral or max or whatever.

Has anyone else seen this before?
Thanks.
