Miscellaneous Applications of Differential Quadrature Method

2000
In the previous chapters, we have described the applications of the DQ method to fluid mechanics and solid mechanics. Apart from these two areas, the DQ method has been applied in many other areas. For the solution of general partial differential equations, Mansell et al. (1993) compared the DQ method with conventional numerical approaches. Tomasiello (

Differential quadrature method for nonlinear fractional partial differential equations

Engineering Computations, 2018
Purpose The purpose of this paper is to propose a method for solving nonlinear fractional partial differential equations on the semi-infinite domain and to get better and more accurate results. Design/methodology/approach The authors proposed a method by using the Chebyshev wavelets in conjunction with differential quadrature technique.

A comparison of differential quadrature methods for the solution of partial differential equations

Computer Methods in Applied Mechanics and Engineering, 1993
First of all the authors present a brief outline of the quadrature discretization method (QDM) as a generalization of standard spectral collocation methods. In fact they propose a discrete representation of the derivative operator for arbitrary subdivisions of the argument domain based on split range polynomial expansions.

Analysis of elliptical waveguides by differential quadrature method

IEEE Transactions on Microwave Theory and Techniques, 2000
A new approach for elliptical waveguide analysis is presented in this paper. This approach applies the global method of a differential quadrature (DQ) to discretize the Helmholtz equation and then reduces it into an eigenvalue equation system. All the cutoff wavelengths from low-to high-order modes can be simultaneously obtained from the eigenvalues of

Inverse Differential Quadrature Method and its Application in Engineering

Inverse Differential Quadrature Method and its Application in Engineering is the first book to comprehensively cover the development of a new numerical solution technique: the inverse differential quadrature method (iDQM), as an indirect approximation technique that can circumvent numerical differentiation-induced errors in the solution of systems of ...

Generalized Differential Quadrature Method for Burgers Equation

Computer Technology and Applications, 2003
The generalized differential quadrature method as an accurate and efficient numerical method is developed for the Burgers equation. The numerical algorithm for this class of problem is presented. Differential quadrature approximation of needed derivatives is given by a weighted linear sum of the function values at grid points.

Stability and accuracy of the iterative differential quadrature method

International Journal for Numerical Methods in Engineering, 2003
AbstractIn this paper the stability and accuracy of an iterative method based on differential quadrature rules will be discussed. The method has already been proposed by the author in a previous work, where its good performance has been shown. Nevertheless, discussion about stability and accuracy remained open.
