Software Development Processes Applied to Computational Icing Simulation

Trade names or manufacturers' names are used in this report for identification only. This usage does not constitute an official endorsement, either expressed or implied, by the National Aeronautics and Space Administration. The development of computatioiral icing simulation methods is making the transition from the research realm to commonplace use in design and certification efforts. As such, standards of code management, design, validation, and documentation must be adjusted to accommodate the increased expectations of the user community wich respect to accuracy, reliability, capability, and usability. This paper discusses these concepts with regard to current and future icing simuiaiiorr code development efsorts as implemented by the Icing Branch of the NASA Lewis Research Center iir collaboraiiori with the NASA Lewis Engineering Design and Analysis Division. With the applkation of the techrriqircs oirtiirted in this paper, the LE WICE ice accretion code has become a more stable and reliable software product.
