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
    ...
}

The inherited entries are elaborated in:

• Foam::fixedValueFvPatchField

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