Detailed Description

Multiplies a given list of (at least two or more) fields and outputs the result into a new field.

    fieldResult = field1 * field2 * ... * fieldN

Operands:

Operand	Type	Location
`input`	vol<Type>Field(s)	$FOAM_CASE/<time>/<inpField>s
`output` field	vol<Type>Field	$FOAM_CASE/<time>/<outField>

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

Usage

Minimal example by using system/controlDict.functions:

multiply1
{
    // Mandatory entries (unmodifiable)
    type    multiply;
    libs    (fieldFunctionObjects);

    // Mandatory (inherited) entry (runtime modifiable)
    fields  (<field1> <field2> ... <fieldN>);

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: multiply	word	yes	-
`libs`	Library name: fieldFunctionObjects	word	yes	-
`fields`	Names of the operand fields	wordList	yes	-

The inherited entries are elaborated in:
