Description🔗
The pressureInletOutletVelocity
is a velocity inlet/outlet boundary
condition that applies a zero-gradient condition for outflow (as defined by
the flux); and obtains velocity from the flux with specified inlet direction.
The tangential patch velocity can be optionally specified.
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type patch;
...
}
Field file🔗
<patchName>
{
// Mandatory entries
type pressureInletOutletVelocity;
// Optional entries
tangentialVelocity <vectorField>;
phi <word>;
// Inherited entries;
...
}
where:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type |
Type name: pressureInletOutletVelocity
|
word | yes | - |
tangentialVelocity |
Tangential velocity field | vectorField | no | Zero |
phi |
Name of flux field | word | no | phi |
The inherited entries are elaborated in:
-
Sign conventions:
- positive flux (out of domain): apply zero-gradient condition
- negative flux (into of domain): derive from the flux with specified direction
