Abstract
Recently some differential quadrature (DQ) based discrete
numerical methods, which are original works and have
perspectives, were proposed by the author. These methods
are generic differential quadrature (GDQ), extended
differential quadrature (EDQ), differential quadrature finite
element method (DQFEM), differential quadrature finite
difference method (DQFDM), differential quadrature
element method (DQEM), generalized differential quadrature
element method (GDQEM) and generalized coordinate
differential quadrature element method (GCDQEM).
They are all based on a strong formulation. These methods
have excellent numerical efficiency and reliability.
Moreover, they have the advantage of consistently discretizing
continuum problems having arbitrarily complex
geometries.
