Dear all,

*Dr. Öğr. Üyesi Nagehan Alsoy-Akgün* from Van Yüzüncü Yıl University will
give a talk titled   *“*  *The numerical solution of 2D sine-Gordon
equation using DRBEM*   ”  on March 12th , at 14:00. All interested are
invited.

Abstract: In this study two-dimensional sine-Gordon equation is solved by
using the dual reciprocity boundary element method (DRBEM). At the
beginning of the solution procedure, central difference approximations are
used for both first and second order time derivatives. After inserting the
finite difference approximations into the governing equation, the form of
the modified Helmholtz equation is obtained. The fundamental solution of
modified Helmholtz equation is employed in the integral equation
formulation. The inhomogeneous terms of the equation cause a domain
integral in the integral equation formulation which leads to loss of
advantage of the method. The DRBEM provides to transform the domain
integral into the boundary integral by approximating the inhomogeneous term
of the with thin plate spline ($r^2ln\,r$).  First, code validation of the
method is done using a test problem and then proposed method is applied for
several cases involving line and ring solitons to show its capability to treat
of the problem. Presented numerical results are observed to be in good
agreement with other numerical results available in the literature.
