Class
    Foam::fv::heatTransferCoefficientModels::function2
 
Description
    Function2 heat transfer model. The 2D function returns the heat transfer
    coefficient as a function of the local and neighbouring velocity
    magnitudes.
 
Usage
    Example usage:
    \verbatim
    {
        heatTransferCoefficientModel function2;
 
        htcFunc
        {
            type        constant;
            value       1e5;
        }
    }
    \endverbatim
