Abstract

The Method of Weighted Residuals (MWR) is used to compare the finite element method (FEM) with the finite volume method (FVM) through nodal recursion relations. Both methods reside under the general MWR structure, with the underlying switch between the two methods established through the weighting function. Both methods yield comparable spatial accuracy for steady-state conditions. However, the flexibility of the FEM permits additional options that can increase accuracy, but generally at the expense of additional time and resource constraints.
