       abstract = "Large-scale numerical simulation is one of the basic blocks in computational
         science and engineering. Researchers in academia and industry rely on highly complex simulation
         codes that are able to simulate even the most complicated physical phenomena. Several approaches are
         possible in order to validate the results of a numerical simulation, such as examining the results
         obtained from different simulation packages. In addition one could analyze the impact of certain
         input parameters on the solution. Such sensitivities of the computed solution can be obtained by
         automatic differentiation, a technique for computing truncation error-free derivatives of functions
         given in the form of a computer program. For a standard flow problem, we examine the results
         obtained from the two simulation packages FLUENT and SEPRAN, and we compare the derivatives which
         are computed by automatic differentiation. We show that, although the two packages employ
         fundamentally different algorithms, the results obtained, i.e., the velocity fields and their
         respective sensitivities, are comparable.",
