    Abstract

    This article presents computer-algebra based techniques for the automatic generation and maintenance of numerical codes based on finite difference approximations. The various generation phases — specification, discretization, implementation and translation — as well as their respective knowledge bases, are discussed and specific attention is given to data mappings in the implementation phase and to high-performance language extensions in the Fortran translation phase. The generation of Fortran source for the dynamics part of a limited area weather forecasting grid-point model is discussed and is illustrated by showing the production of a few variants of the surface-pressure tendency code using the present prototype. Finally, we indicate briefly how adjoints can be obtained using the present methodology.
