I am solving pressure poisson eqn for N-S eqns for unconfined flow.
I want to solve a laminar 1D flow with that by using 1 cell in x & y axis and 300 cells in z dir. I am specifying a velocity at inlet and neuman BC for outlet. Is this approach correct? What should be my BCs with respect to pressure for? x-y(inlet & outlet) x-z(top & bottom) y-z(side faces) What should be my BCs with respect to velocity for? x-z(top & bottom) y-z(side faces) Thanks in advance |

Thank you for the reply.
Can you please explain what empty does theoretically to the velocity and pressure? |
