Detailed Description

Limits input fields to user-specified min and max bounds.

Operands:

Operand	Type	Location
`input`	vol<Type>Field	$FOAM_CASE/<time>/<inpField>
`output` file	-	-
`output` field	vol<Type>Field	$FOAM_CASE/<time>/<outField>

where <Type>=Scalar/Vector/SphericalTensor/SymmTensor/Tensor.

Note: For non-scalar types of input field, the user limit is used to create a scaling factor using the field magnitudes.

Usage

Minimal example by using system/controlDict.functions:

limitFields1
{
    // Mandatory entries (unmodifiable)
    type            limitFields;
    libs            (fieldFunctionObjects);

    // Mandatory entries (runtime modifiable)
    fields          (U);
    limit           max;
    max             100;

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Req'd	Dflt
`type`	Type name: limitFields	word	yes	-
`libs`	Library name: fieldFunctionObjects	word	yes	-
`fields`	List of fields to process	wordList	yes	-
`limit`	Bound to limit - see below	word	yes	-
`min`	Min limit value	scalar	conditional	-
`max`	Max limit value	scalar	conditional	-

Options for the limit entry:

        min  : specify a minimum value
        max  : specify a maximum value
        both : specify a minimum value and a maximum value

The inherited entries are elaborated in:

functionObject.H

Usage by the postProcess utility is not available.
