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.

Differential quadrature: a powerful new technique for analysis of composite structures
Composite Structures, 1997Beginning with the original work of Richard Bellman and his associates, the differential quadrature method is now recognized as an alternate numerical solution technique for the initial and boundary value problems of engineering and applied sciences. This paper presents an up-to-date account of the works in which the differential quadrature method has ...

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 ...

Abstract The main aim of the current paper is to propose an efficient numerical procedure based on the meshless method for solving some models of conservation laws. In the current investigation, we combine the upwind local radial basis function-differential quadrature (LRBF-DQ) method with the space-splitting idea for solving some conservation laws ...

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.

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.
