Define_execute_at_end

Hi,

It is written in the UDF Manual that DEFINE_ADJUST macro is utilized in order to manipulate the flow variables, and it is called at the beginning of the each iteration or time step.

Can DEFINE_EXECUTE_AT_END macro be also used in order to change the flow variables, in particular velocity? As far as I understood, their difference is their sequence in the solution process. DEFINE_EXECUTE_AT_END macro is called at the end of the steady state iteration, or at the end of the time step; whereas DEFINE_ADJUST is at the beginning of them.

Can anybody clarify that?

Thanks in advance.
