Computational fluid dynamics by boundary–domain integral method

open access: yesInternational Journal for Numerical Methods in Engineering, 1999
Summary: We present a boundary-domain integral method for the solution of general transport phenomena in incompressible fluids governed by Navier-Stokes equations. Velocity-vorticity formulation of the conservation equations is employed. Different integral representations for conservation field functions based on different fundamental solutions are ...

Application of DRBEM for 2D sine-Gordon equation

open access: yesJournal of Taibah University for Science, 2021
This research paper introduces an application of dual reciprocity boundary element method (DRBEM) for the solution of sine-Gordon equation (SGE) in two-space dimension. Initially, the time derivatives are expanded using central difference schemes.

A natural boundary element method for the Sobolev equation in the 2D unbounded domain

open access: yesBoundary Value Problems, 2017
In this article, we devote ourselves to establishing a natural boundary element (NBE) method for the Sobolev equation in the 2D unbounded domain. To this end, we first constitute the time semi-discretized super-convergence format for the Sobolev equation

A FEM-Green Approach for Magnetic Field Problems with Open Boundaries

open access: yesMathematics, 2021
A new finite element method/boundary element method (FEM/BEM) scheme is proposed for the solution of the 2D magnetic static and quasi-static problems with unbounded domains. The novelty is an original approach in the treatment of the outer region.
