Gauss integral point
In numerical analysis, a quadrature rule is an approximation of the definite integral of a function, usually stated as a weighted sum of function values at specified points within the domain of integration. (See numerical integration for more on quadrature rules.) An n-point Gaussian quadrature rule, named after Carl Friedrich Gauss, is a quadrature rule constructed to yield an exact result for po… Weborder.

The expression “full integration” refers to the number of Gauss points required to integrate the polynomial terms in an element's stiffness matrix exactly when the element has a regular shape. For hexahedral and quadrilateral elements a “regular shape” means that the edges are straight and meet at right angles and that ...

WebGauss quadrature aims to find the “least” number of fixed points to approximate the integral of a function such that: where and . Also, is called an integration point and is called the associated weight. The number of integration points and the associated weights are chosen according to the complexity of the function to be integrated.
