Unhappy UDF profile function of iteration

nando83 is on a distinguished road
Hi, I'm a newbie with UDF.
I'd like to impose as boundary condition a static pressure value depending on flow properties. (Sorry for my bad english )
I'd like Fluent computes, every iteration, the values of total pressure, total temperature and mass flow rate on a boundary surface and uses this values to compute a value for the static pressure to be imposed on that surface.
Is correct to use DEFINE_PROFILE?How can I change the profile every iteration?
Thank you.
