An efficient and robust pressure correction projection method with the CNMT1 finitedifference scheme is presented in this paper for the numerical solution of the incompressible Navier-Stokes equation
In this paper some finite difference schemes with intrinsic parallelism for nonlinearparabolic system are constructed. For the nonlinear difference system with intrinsic parallelism, a mild restrictio
In this paper, a method for shape-preserving interpolation is presented. By insertingsome new knots, a C~k (k> 2) shape-preserving interpolating spline function of degree 2k+1is obtained. The errors o
This paper presents a new divide-and-conquer algorithm for the eigenvalue problem ofsymmtric tridiagonal matrices. The new algorithm bases on bisection and secant iteration,which is different from Cup
Using Bezier curves of degree n + 1 as design curves XA(t) on one plane and Bezier curves of degree n + m + 1 as adjoint curves XB(t) on another parallel plane, the conditions of constructing developa
In this paper, a non-matching non-overlapping domain decomposition method for solving 3-dimensional problems is presented. Based on the method, we developed a powerful software which is suitable for s
In this paper, a BEM model for transient heat transfer with phase-front as a mov-ing boundary is presented. A new time-marching scheme together with the analytical treatment of integrals for the diffu
SLMQN is a subspace limited memory quasi-Newton algorithm for solving largescale bound constrained nonlinear programming problems. The algorithm is suitable to these large problems in which the Hessia
This paper describes a vector algorithm for some branched functions-indirect address algorithm, and the results of numerical experiments on C3201 computer and YH-2 computer are also given.
A new finite volume scheme, based on first order monotone scheme and limited linear reconstruction, is constructed for scalar hyperbolic conservation laws in two dimension,the scheme satisfies the max
