Studies on the Method of Orthogonal Collocation IV. Laguerre and Hermite Orthogonal Collocation Method

open access: yesJournal of King Saud University: Engineering Sciences, 2000
Differential equations for which the zeros of Laguerre and Hermite polynomials are suitable collocation points are identified. It is shown that the equations representing tubular reactors with axial dispersion can be solved efficiently using the zeros of

Quintic B-spline collocation method for numerical solution of free vibration of tapered Euler-Bernoulli beam on variable Winkler foundation

open access: yesJournal of Mechanical Engineering and Sciences, 2021
The collocation method is the method for the numerical solution of integral equations and partial and ordinary differential equations. The main idea of this method is to choose a number of points in the domain and a finite-dimensional space of candidate ...

ISOGEOMETRIC COLLOCATION METHODS [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2010
We initiate the study of collocation methods for NURBS-based isogeometric analysis. The idea is to connect the superior accuracy and smoothness of NURBS basis functions with the low computational cost of collocation. We develop a one-dimensional theoretical analysis, and perform numerical tests in one, two and three dimensions.

Reduced Collocation Methods: Reduced Basis Methods in the Collocation Framework [PDF]

open access: yesJournal of Scientific Computing, 2012
In this paper, we present the first reduced basis method well-suited for the collocation framework. Two fundamentally different algorithms are presented: the so-called Least Squares Reduced Collocation Method (LSRCM) and Empirical Reduced Collocation Method (ERCM). This work provides a reduced basis strategy to practitioners who {prefer} a collocation,
