Multiplies a given list of (at least two or more) fields and outputs the
result into a new field.
fieldResult = field1 * field2 * ... * fieldN
Minimal example by using \c system/controlDict.functions:
multiply1
{
// Mandatory entries (unmodifiable)
type multiply;
libs (fieldFunctionObjects);
// Mandatory (inherited) entry (runtime modifiable)
fields (<field1> <field2> ... <fieldN>);
...
}
