-------- 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.
