surfaceNormalFixedValue

Description

The surfaceNormalFixedValue is a boundary condition that provides a surface-normal vector boundary condition by its magnitude.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            surfaceNormalFixedValue;
    refValue        <scalarField>;

    // Optional entries
    ramp            <Function1<scalar>>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: surfaceNormalFixedValue	word	yes	-
refValue	Reference value fiueld	scalarField	yes	-
ramp	Time-based ramping	Function1<scalar>	no	-

The inherited entries are elaborated in:
