Macros and UDF in Fluent
 

Hi,

I am running a simulation in Fluent and this simulation will take me 5 hrs. Basically at the end of the simulation, I go to boundary conditions and change just the inlet velocity. And ofcourse, I would write data and case files in a separate folder.

I can use a macro to input the veloctiy and start the iteration process. But what I want is at the end of the simulation, this macro should be called and executed automatically (I can set 5 or 6 different macros to input 6 different velocitis in boundary condition). I was reading about 2.2.3 DEFINE_EXECUTE_AT_END and I don't know how to use it.

Is there anybody in the forums that can advise me how to achieve this feat? Thanks
