Explore: Spectral Element

differential equations, a topic in mathematics, the spectral element method (SEM) is a formulation of the finite element method (FEM) that uses high-degree piecewise

finite element method. Spectral element methods combine the geometric flexibility of finite elements and the acute accuracy of spectral methods. Spectral methods

possible. Spectral methods and finite-element methods are closely related and built on the same ideas; the main difference between them is that spectral methods

function space cannot be represented on a discrete spectral element mesh; this is where the spectral element discretization begins. The most crucial thing

A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. It may result from emission or absorption of light in a

equation. Spectral methods and finite element methods are closely related and built on the same ideas; the main difference between them is that spectral methods

Pseudo-spectral methods, also known as discrete variable representation (DVR) methods, are a class of numerical methods used in applied mathematics and

Nek5000 is a highly scalable spectral element computational fluid dynamics code for solving the incompressible Navier-Stokes equations on 2D quadrilateral

relations in steps 3 and 4. The spectral method is similar to the finite element method. The major difference is that spectral method uses basis functions

large-scale subsurface structures. Some models depend on the use of the spectral element method, which take into account the effects of self-gravitation because
