Is There a Difference in the Finite Element Method?
Abstract
The finite element approximation of the convective diffusive transport equation can be expressed in terms of well-known finite difference notation. Examination of the relationship obtained reveals that in contrast to finite difference schemes, which approximate the differential equation at a point, the finite element method can be interpreted as an approximation of the integrated form of this equation.
