Class
    Foam::UniformDimensionedField
 
Description
    Dimensioned<Type> registered with the database as a registered IOobject
    which has the functionality of a uniform field and allows values from the
    top-level code to be passed to boundary conditions etc.
 
    Is a 'global' field, same on all processors
