Least-squares finite element method for the advection-diffusion equation

Dağ, Idris; Irk, D; Tombul, M (Elsevier Science Inc, 2006)

The space-time least-squares finite element methods are constructed for the advection-diffusion equation by using both linear shape functions and quadratic B-spline shape functions. Two test problems are studied to demonstrate ...
Numerical solution of RLW equation using radial basis functions

Dağ, Idris; Dereli, Yılmaz (Taylor & Francis LTD, 2010)

The numerical solution of the regularized long wave equation is investigated by means of the meshless method based on collocation with the well-known radial basis functions (RBFs). Single solitary wave motion, two solitary ...
Numerical solutions of KdV equation using radial basis functions

Dağ, Idris; Dereli, Yılmaz (Elsevier Science Inc, 2008)

Numerical solution of the Korteweg-de Vries equation is obtained by using the meshless method based on the collocation with radial basis functions. Five standard radial basis functions are used in the method of the ...
Soliton solutions for NLS equation using radial basis functions

Dereli, Yılmaz; Irk, Dursun; Dağ, Idris (Pergamon-Elsevier Science LTD, 2009)

We present a numerical study of the cubic nonlinear Schrodinger equation by using the meshless method based on collocation with radial basis functions. The method is examined for the single soliton solution and interaction ...
