I'm not aware that Fluent can model this using its standard boundary conditions - you might need to code it as a UDF. Although I have experience at writing UDFs I would not know how to change boundary condition types while Fluent is running.

If your BC is unsteady, then you can change the type of your BC, by using a dynamic mesh fonctionnality. (events) I never used it, but I think you can do something with that. http://www.engres.odu.edu/Applicatio...e403.htm#58606
