This velocity inlet/outlet boundary condition is applied to velocity boundaries where the pressure is specified. A zero-gradient condition is applied for outflow (as defined by the flux); for inflow, the velocity is obtained from the patch-face normal component of the internal-cell value.

This velocity inlet/outlet boundary condition is applied to velocity boundaries where the pressure is specified. A zero-gradient condition is applied for outflow (as defined by the flux); for inflow, the velocity is obtained from the patch-face normal component of the internal-cell value.
The tangential patch velocity can be optionally specified.
- Usage
| Property | Description | Required | Default value |
phi | flux field name | no | phi |
tangentialVelocity | tangential velocity field | no | |
Example of the boundary condition specification:
<patchName>
{
type pressureInletOutletVelocity;
phi phi;
tangentialVelocity uniform (0 0 0);
value uniform (0 0 0);
}- Note
- Sign conventions:
- positive flux (out of domain): apply zero-gradient condition
- negative flux (into of domain): derive from the flux in the patch-normal direction
