uniformNormalFixedValue

Description

The uniformNormalFixedValue is a boundary condition that provides a uniform surface-normal vector 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            uniformNormalFixedValue;
    uniformValue    <PatchFunction1<Type>>;

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

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: uniformNormalFixedValue	word	yes	-
uniformValue	Patch field values	PatchFunction1<Type>	yes	-
ramp	Time-variant ramp	Function1<scalar>	no	-

The inherited entries are elaborated in:

• fixedValueFvPatchField.H
• PatchFunction1.H
• Function1.H

• Sign conventions:
  • the value is positive for outward-pointing vectors
