Abstract:
      In this paper,a new method DQDDM(Differential Quadrature Domain Decomposition Method) is presented.We divide the computational domain into several non-overlapping subdomains,and DQM is applied in each subdomains respectively.Numerical boundary reduction technique independent of the basic solution of the differential equation is used.By eliminating the interior points and combining with the block matrix technique,the differential equation is reduced to linear algebraic equations which include the boundary points only.The complexity of the computation is reduced greatly.The numerical results are satisfactory.
