Class
    Foam::Function1s::Coded
 
Description
    Constructs a dynamically compiled Function1.
 
Usage
    Example of a cosine bell shaped pulse inlet:
    \verbatim
    inlet
    {
        type            uniformFixedValue;
        uniformValue    coded;
 
        name            pulse;
 
        codeInclude
        #{
            #include "mathematicalConstants.H"
        #};
 
        code
        #{
            return vector
            (
                0.5*(1 - cos(constant::mathematical::twoPi*min(x/0.3, 1))),
                0,
                0
            );
        #};
    }
    \endverbatim
