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.
