Class
    Foam::functionEntries::calcIncludeEntry
 
Description
    Specify an include file for #calc, expects a single string to follow.
 
    For example if functions from transform.H are used in the #calc expression
    \verbatim
    angleOfAttack   5; // degs
 
    angle           #calc "-degToRad($angleOfAttack)";
 
    #calcInclude    "transform.H"
    liftDir         #calc "transform(Ry($angle), vector(0, 0, 1))";
    dragDir         #calc "transform(Ry($angle), vector(1, 0, 0))";
    \endverbatim
 
    The usual expansion of environment variables and other constructs
    (eg, the \c ~OpenFOAM/ expansion) is retained.
