Detailed Description

Intermediate class for handling field expression function objects (e.g. blendingFactor etc.) whereinto a single field is input.

Usage

Minimal example by using system/controlDict.functions:

<functionObject>
{
    // Mandatory and optional entries
    ...

    // Inherited entries
    field             <field>;
    result            <fieldResult>;
    cellZones         ( <cellZone1> <cellZone2> ... <cellZoneN> );
    nLayers           <label>;
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`field`	Name of the operand field	word	yes	-
`result`	Name of the output field	word	no	<FO>(<field>)
`cellZones`	Names of cellZones	wordRes	no	-
`nLayers`	Number of cell layers around cellZones	label	no	0
