pressureInletVelocity

Description

The pressureInletVelocity is a velocity boundary condition where the inflow velocity is obtained from the flux with a direction normal to the patch faces.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type           pressureInletVelocity;

    // Optional entries
    phi            <word>;
    rho            <word>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: pressureInletVelocity	word	yes	-
phi	Name of the flux field	word	no	phi
rho	Name of the density field	word	no	rho

The inherited entries are elaborated in:

• Foam::fixedValueFvPatchField

• If reverse flow is possible or expected use the pressureInletOutletVelocity condition instead.
