Can some body show me how to write inlet and outlet boundary condition in FORTRAN? thanks

tell me your geometry of yoyr flow domain and what type of boundary condiitions you want to employ. Whether your problem is flow problem or something else. try to give full discription.

-------- my problem is just like the figure above. it's a deadhead pipe(2D) with two oulets. suppose that V=-x*x, A and BB are oulets. I want to find the some relationship between them, such as velocity, vorticity, steamline and flowrate at A and BB(BB is larger than A).the model uses imcompressiable N-S Function. Can you tell me how to write the B.C. in Fortran or C++/C? Thanks.
