Accuracy improvement of collocation method by using the over-range collocation points for 2-D and 3-D problems

open access: yesMechanical Engineering Journal, 2014
It has been shown that the significance of the positivity conditions in the collocation methods (CM), and the violation of the positivity conditions can significantly result in a large error in the numerical solution.

A meshfree point collocation method for elliptic interface problems [PDF]

open access: yesApplied Mathematical Modelling, 2023
We present a meshfree generalized finite difference method for solving Poisson's equation with a diffusion coefficient that contains jump discontinuities up to several orders of magnitude. To discretize the diffusion operator, we formulate a strong form method that uses a smearing of the discontinuity; and a conservative formulation based on locally ...

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 ...
