Description
|
|
This velocity inlet/outlet boundary condition is applied to pressure
|
|
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.

Property | Description | Required | Default value
|
|
phi | flux field name | no | phi
|
|
tangentialVelocity | tangential velocity field | no |
|
|
\endtable
|
|
|
|
Example of the boundary condition specification:
|
|
\verbatim
|
|
myPatch
|
|
{
|
|
type pressureInletOutletVelocity;
|
|
phi phi;
|
|
tangentialVelocity uniform (0 0 0);
|
|
value uniform 0;
|
|
}
|
|
\endverbatim
|
|
|
|
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
