چکیده
Abstract An extended second order finite difference method on a variable mesh is proposed for the solution of singularly perturbed boundary value problem. A discrete equation achieved non uniform by extending first and derivatives to higher differences. This solved efficiently using tridiagonal solver. The analysed convergence, convergence derived. Model examples are scheme compared with available methods in literature uphold method.

Moving Mesh Non-standard Finite Difference Method for Non-linear Heat Transfer in a Thin Finite Rod
In this paper, a moving mesh technique and a non-standard finite difference method are combined, and a moving mesh non-standard finite difference (MMNSFD) method is developed to solve an initial boundary value problem involving a quartic nonlinearity that arises in heat transfer with thermal radiation. In this method, the moving spatial grid is obtained by a simple geometric adaptive algorithm ...
متن کاملA Fitted Second Order Finite Difference Method for Singular Perturbation Problems Exhibiting Dual Layers
Abstract In this paper a fitted second-order finite difference method is presented for solving singularly perturbed two-point boundary value problems with the boundary layer at both end (left and right) points. We have introduced a fitting factor in second-order tri-diagonal finite difference scheme and it is obtained from the theory of singular perturbations. The efficient Thomas algorithm is ...
متن کاملUniformly convergent non-standard finite difference methods for self-adjoint singular perturbation problems
We design non-standard finite difference schemes for self-adjoint singularly perturbed two-point boundary value problems. Essential physical properties (e.g., dissipativity) of the solutions of such problems are captured in the schemes by an appropriate renormalization of the denominator of the discrete derivative. The schemes are analyzed for -uniform convergence. Several numerical examples ar...
متن کاملA finite difference moving mesh method based on conservation for moving boundary problems
We propose a velocity-based moving mesh method in which we move the nodes so as to preserve local mass fractions. Consequently, the mesh evolves to be finer where the solution presents rapid changes, naturally providing higher accuracy without the need to add nodes. We use an integral approach which avoids altering the structure of the original equations when incorporating the velocity and allo...
متن کاملA New Efficient Spectral Galerkin Method for Singular Perturbation Problems∗
A new spectral Galerkin method is proposed for the convection-dominated convection-diffusion equation. This method employs a new class of trail function spaces. The available error bounds provide a clear theoretical interpretation for the higher accuracy of the new method compared to the conventional spectral methods when applied to problems with thin boundary layers. Efficient solution techniq...
