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 -
