change the boundary condtion in every iteration
 

Hello everyone, i have two problem about UDF function:
(1) Can i use DEFINE_ADJUST marco of UDF to change the boundary condition?
(2) If i use the Macro of DEFINE_PROFILE,DEFINE_INI,DEFINE_ADJUST and DEFINE_SOURCE in a UDF function, what is the Calling Sequence of these Macro in the FLUENT Solution Process?

I would very appreciate someone could help me resolve these puzzles.
