NEW HYBRID-STREAMLINE-UPWIND FINITE-ELEMENT METHOD IN DUAL SPACE (FUNDAMENTAL THEORY AND DISCRETE DEL OPERATOR)

This paper presents a new hybrid-streamline-upwind finite-element method which is based on the finite analytic method developed in the field of finite difference analysis. In order to obtain an optimal shape function, an adjoint differential operator is introduced to the differential operator for a steady advection-diffusion equation. The shape functions which satisfy these differential operators are mutually dual. One of them accurately interpolates the functions appearing in convection-dominate flows, and the other becomes a hybrid- streamline-upwind weight function. Also, a discrete del operation is defined for the reduction of memory storage in computers.
