Class
    Foam::DimensionedFieldFunctions::FieldFunction
 
Description
    Field function which looks up another field and uses it as the argument to
    evaluate a given Foam::Function1. The user must specify both the name of
    the looked-up field and the function1.
 
Usage
    To create a temperature dependent electrical conductivity in the
    \c solidElectricalConduction fvModel:
    \verbatim
    solidElectricalConduction
    {
        type        solidElectricalConduction;
 
        sigma
        {
            type        fieldFunction;
            field       T;
            function
            {
                type        polynomial;
                coeffs      (7.61e7 -1.38e5);
            }
        }
    }
    \endverbatim
