Finite Element Methods

Finite Element Methods

In mathematics, finite element method (FEM) is a numerical technique for finding approximate solutions to boundary value problems. It uses variational methods (the Calculus of variations) to minimize an error function and produce a stable solution. Analogous to the idea that connecting many tiny straight lines can approximate a larger circle, FEM encompasses all the methods for connecting many simple element equations over many small subdomains, named finite elements, to approximate a more complex equation over a larger domain.

Famous quotes containing the words methods, finite and/or element:

    All men are equally proud. The only difference is that not all take the same methods of showing it.
    François, Duc De La Rochefoucauld (1613–1680)

    We know then the existence and nature of the finite, because we also are finite and have extension. We know the existence of the infinite and are ignorant of its nature, because it has extension like us, but not limits like us. But we know neither the existence nor the nature of God, because he has neither extension nor limits.
    Blaise Pascal (1623–1662)

    The reverence for the Scriptures is an element of civilization, for thus has the history of the world been preserved, and is preserved.
    Ralph Waldo Emerson (1803–1882)
