Nonreflecting BC/Pressure Outlet
 

Hey,

I am simulating a pressure wave into a square domain. When the pressure wave reaches the outlet, there is a reflection of it.
I use a real gas model and the NRBC option isn't available in boundary conditions!!!!
I use a compressible flow and there is none boundary conditions for me in fluent.
So, I want to hook it in a UDF with a define_profile but if anyone had ever do this mau=y he can help me, please?
Thanks!!!

This is my pressure wave. I a have a lot of problem when it reaches the wall(pressure outlet)
