         functions given in the form of a high-level programming language such as Fortran, C, or~C++. The
         program is treated as a sequence of elementary statements to which the chain rule of differential
         calculus is applied mechanically. A key feature of this technique is its ability to generate
         accurate derivatives rather than approximations obtained from numerical differentiation like divided
         differences. We survey automatic differentiation and report on preliminary results that have been
         obtained applying the automatic differentiation tool ADIFOR to a large-scale computational fluid
         dynamics solver, TFS, developed at Aerodynamisches Institut, Aachen University of Technology. This
         solver comprises approximately 24,000 lines of Fortran~77 and is able to resolve steady and unsteady
         laminar and turbulent flows in two and three dimensions.",
