A local radial basis function differential quadrature semi-discretisation technique for the simulation of time-dependent reaction-diffusion problems

Engineering Computations, 2021
Purpose This paper aims to develop a meshfree algorithm based on local radial basis functions (RBFs) combined with the differential quadrature (DQ) method to provide numerical approximations of the solutions of time-dependent, nonlinear and spatially one-dimensional reaction-diffusion systems and to capture their evolving patterns.

Differential quadrature: A technique for the rapid solution of nonlinear partial differential equations

Journal of Computational Physics, 1972
Abstract The numerical solution of nonlinear partial differential equations plays a prominent role in numerical weather forecasting, optimal control theory, radiative transfer, and many other areas of physics, engineering, and biology. In many cases all that is desired is a moderately accurate solution at a few points which can be calculated rapidly.

INTERPOLATION TECHNIQUES FOR SCATTERED DATA BY LOCAL RADIAL BASIS FUNCTION DIFFERENTIAL QUADRATURE METHOD

International Journal of Computational Methods, 2013
Interpolation techniques based on the local radial basis function differential quadrature (LRBF-DQ) method are proposed to interpolate the field values with arbitrarily given scattered data. The interpolation of more unknown field data from the limited known data is becoming an important research subject nowadays for the large-scale engineering ...

Simulation of activator–inhibitor dynamics based on cross-diffusion Brusselator reaction–diffusion system via a differential quadrature-radial point interpolation method (DQ-RPIM) technique

The European Physical Journal Plus, 2021
The current paper proposes an efficient numerical procedure for solving the two-dimensional Brusselator reaction–diffusion system. First, the time derivative is discretized by a semi-implicit finite difference scheme such that the nonlinear terms are approximated by using one term of the Taylor expansion.

Finite difference discretizations by differential quadrature techniques

Communications in Numerical Methods in Engineering, 1999
The author proposes procedures for developing a finite difference method discretization by using differential quadrature and generic differential quadrature methods. The proposed method uses weighting coefficients for differential quadrature. Generic differential quadrature derivation of finite difference operators is studied, too. One-, two- and three-

A comparative study of differential quadrature and cubature methods vis-à-vis some conventional techniques in context of convection-diffusion-reaction problems

Chemical Engineering Science, 1995
Abstract This paper presents a comprehensive comparative study of the differential quadrature and cubature methods in relation to the conventional techniques of the finite difference and finite element methods. The basis of comparison is the numerical accuracy and the computational efficiency in terms of CPU time.
