Hydrodynamic boundary conditions used.
| Surface | Type | Description | Specifications |
|---|---|---|---|
| Inlet | Velocity inlet | Velocity inlet boundary conditions are used to define the flow velocity at flow inlets. The pressure is not fixed, but will change to whatever value is necessary to provide the prescribed velocity profile. | Ux = 0 Uy = 0 Uz = case dependent |
| Outlet | Pressure outlet | A gauge pressure is specified at the outlet. The velocity gradients are fixed to zero. | p = fixed arbitrary value |
| Wall | Wall | No-slip condition is imposed. | Ui|wall = 0 |
