edgeNormalFixedValue

Description

The edgeNormalFixedValue is a boundary condition that provides an edge normal fixed value vector field for finite area calculations.

This condition describes 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            edgeNormalFixedValue;
    refValue        <scalarField>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: edgeNormalFixedValue	word	yes	-
refValue	Edge-normal velocity field	scalarField	yes	-

The inherited entries are elaborated in:

• fixedValueFaPatchFields.H

• The value is positive for outward-pointing vectors.
