Class
    Foam::UFunctionalDimensionedField
 
Description
    Combined class containing a field reference, a dimensionedField wrapper
    providing the corresponding mesh and dimensions and a run-time selected
    function to evaluate and update the field.
 
    Particularly applicable to time and/or space varying boundary conditions.
