ABSTRACT (Maximum 200 words) The development of compukilional icing simulation methods is making the transition from the research realm to common- place use in design and ccrlilicaiion cl’hrts. As such. standards of code management, design, validation, and documenta- tion must be adjusted to acco~iinioda~c thc increased expectations of the user community with respect to accuracy, reliability, capability. and usahility. This paper discusses these concepts with regard to current and future icing simulation code development efforts as implemented by the Icing Branch of thc NASA Lewis Research Center in collaboration with the NASA Lewis Engineering Design and Analysis Division. With the application of the techniques outlined in this paper. the LEWICE ice accretion code
