Detailed Description

Computes blending factor as an indicator about which of the schemes is active across the domain.

Blending factor values mean:

  0   =  scheme 0
  1   =  scheme 1
  0-1 =  a blending factor between scheme 0 and scheme 1

Operands:

Operand	Type	Location
`input`	-	-
`output` file	dat	$FOAM_CASE/postProcessing/<FO>/<time>/<file>
`output` field	volScalarField	$FOAM_CASE/<time>/<outField>

Usage

Minimal example by using system/controlDict.functions:

blendingFactor1
{
    // Mandatory entries
    type            blendingFactor;
    libs            (fieldFunctionObjects);
    field           <field>;

    // Optional entries
    phi             phi;
    tolerance       0.001;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: blendingFactor	word	yes	-
`libs`	Library name: fieldFunctionObjects	word	yes	-
`field`	Name of the operand field	word	yes	-
`phi`	Name of flux field	word	no	phi
`tolerance`	Tolerance for number of blended cells	scalar	no	0.001

The inherited entries are elaborated in:

Usage by the postProcess utility is not available.

Note

The blendingFactor function object overwrites the DEShybrid:Factor field internally when blendedSchemeBase debug flag is active. However, users are allowed to write out the original DEShybrid:Factor field by executing the writeObjects function object before any blendingFactor function object execution.
