The Research of Grid Technologies on Building Financial Grid;

The financial grid can provide the sharing,inter-linkage,inter-operation of wide-area and heterogeneous information,and more resource sharing by integrateing heterogeneous computers of financial system with the grid technology.

We in this paper present a composite grid method based on the system of finite element program generator(denoted by FEPG)to solve finite element problems with local singularity,which often occurs in engineering and scientific computing.

This paper presents a composite grid method to solve contact problem,which often occurs in the hydraulic structure calculation.

Numerical simulation of flow and pollutants in the north branch of Changjiang estuary by hybrid grids flux difference splitting scheme;

Using preconditioning method to simulate steady/unsteady flows at all speeds on hybrid grids;

Flow simulation of missile with grid fins using structured-unstructured hybrid grids;

Numerical simulation of hypersonic viscous flow with chemical non-equilibrium effects on hybrid grid;

In the numerical simulations of aerocraft′s drag,huge hybrid grids with order of million grid points are necessary,and sometimes super hybrid grids whose grid points are more than ten million are required.

Based on Jameson s finite volume method,an Euler equation solver with high precision hybrid grid is developed to calculate the aerodynamic characteristics of ejection escape system with complex,non-regular and non-streamline shape.
