A modification on the exponential cubic B-spline for numerical
simulation of hyperbolic telegraph equations
Abstract
In this paper, the differential quadrature method is implemented to find
the numerical solution of two and three-dimensional telegraphic
equations with Dirichlet and Neumann’s boundary values. This technique
is according to exponential cubic B-spline functions. So, a modification
on the exponential cubic B- spline is applied in order to use as a basis
function in the DQ method. Therefore, the Telegraph equation (TE) is
altered to a system of ordinary differential equations (ODEs). The
optimized form of Runge-Kutta scheme has been implemented by four-stage
and three-order strong stability preserving (SSP-RK43) to solve the
resulting system of ODEs. We examined the correctness and applicability
of this method by four examples of the TE.
