Comparison of Finite-Difference, Finite-Element, and Spectral Methods,ave gone in two radically different directions. First, finite-element methods use local, low-order polynomial trial functions to generate sparse algebraic equations in terms of meaningful nodal unknowns. Secondly the use of global, orthogonal trial functions permits spectral methods to achieve a hig

Generalized Galerkin Methods,de at which the function is centered. The steady, two-dimensional convection-diffusion equation is.where . is the property being convected and . and . are the velocity components. If the algebraic equations associated with each node are put into a matrix form, the entries on the diagonal only have c

Stochastic Differential Systemsd mass transfer, acoustics, microwave theory, neutron transport, etc. Problems governed by ordinary differential equations, partial differential equations, and integral equations have been investigated via a Galerkin formulation. Steady, unsteady, and eigenvalue problems have proved to be equally amenable to a Galerkin treatment. Essentially, ..

Hans Jürgen Engelbert,Wolfgang Schmidtrly 1970s. The rise in the popularity of the Galerkin formulation and the concurrent decline in popularity of the variational finite-element formulation has coincided with the diversification of the finite-element method into areas remote from the structural birthplace of the method.

Stochastic Differential Systems methods, which were discussed in chapters 3 and 4. Finite-element methods are characterized by the use of local, low-order polynomials as test and trial functions in subdomains called finite elements.
