Abstract

Part of the Software Engineering Methods for Parallel Scientific Applications project[1]1 is investigating object-oriented methods for scientific computing. A commercial real-world Fortran 77 computational fluid dynamics (CFD) application is being redesigned in C++ and Java. This redesign uses newly developed numerical objects rather than the existing arrays of the Fortran 77 code. This paper describes the improved C++ version of the numerical solver for the CFD program. Although this C++ solver code is superior to the Fortran 77 code in problem abstraction straction and computational flexibility, the increase in execution time is small and depends on the machine architecture and compiler software used.
