| Abstract: | The differential quadrature (DQ) is generalized. Various methods for generating the weighting coefficients are developed. The design of a grid model is flexible. Weighting coefficients for general multi-coordinate grid models with arbitrary configurations can also be calculated. The calculation of weighting coefficients is easy. Sample numerical procedures for constructing one-coordinate, two-coordinate and arbitrary finite-coordinate generic differential quadrature models are presented. This revised version was published online in June 2006 with corrections to the Cover Date. |
