The situation is:
The fluid flows in a channel. And the velocities at the inlet are equal to velocities at the outlet. How can I implement this condition in the FlexPDE?
We can not use periodic boundary conditions. Because the pressures are not the same in inlet and outlet. |

Mass conservation should guarantee that the same amount of fluid flows out as flows in.
If the inlet and outlet are the same size, then the velocities should be equal automatically. |
