Introduction In recent years, a few research groups have been developing and evaluating their computational methods, including both CFD and CSD ones, by using unique FV methods [1-4].
A new matrix-free implicit unstructured multigrid finite volume (FV) solver for structural dynamics was presented by Xia et al. [3] for incompressible flow FSI computation and a similar method was developed by Lv et al. [4] for compressible flow FSI simulation.
For all of the grids the simulation is performed by exerting the same load on the right tip of the cantilever until the solution is converged.
The calculation of case 2 give a perfect results compared with those obtained in case1 which means the boundary conditions do really affect the simulation results.

The numerical simulation of hot forming is implemented [1,9].
The cooling system in the hot forming tool is analyzed with the method of computational fluid dynamics (CFD) [10-11].
Both experimental and simulation methods can be adopted to evaluate the impact resistance of hot forming parts and conduct optimization design.
Commercial software LS-DYNA is employed for the simulation, and the impact velocity is 50km/h.

Box 7201, 100074 Beijing, China acnbuaa@sina.cn, blyf545@sohu.com, clord.p@163.com Keywords: Numerical simulation; Preconditioning; Steady flow; Unsteady flow Abstract.
Preconditioning techniques have become established as a useful technique for optimizing accuracy and efficiency of CFD solutions over a range of flow conditions.
However, numerical results by using time-dependent method are not satisfied in the simulation of low Mach number flows.

The numerical simulation approach addresses unsteady Reynolds-averaged N-S solutions and covers transition prediction for unsteady mean flows.
In the numerical simulation, a coupled solver is used; fluid material is supposed to be ideal gas; momentum is in the form of second-order upwind dispersed mode; pressure and velocity coupling uses the SIMPLE algorithm and airfoil surface is the no-slip thermal isolation boundary.

To explore fluid-thermal analysis of the flow fields of front-box and One-spacer nozzle of aluminum roll-casting, a three-dimensional finite element simulation model has been developed to provide analyzing distribution of velocity and temperature of outlet of nozzle, by using coupled fluid-thermal FEM simulation of FLOTRAN module in ANSYS 6.0.
Accounting of both the nozzle and front-box fields will yield more accurate simulation results.
Based on industrial experiments and simulation, one-spacer nozzle has potential capacities to be designed for higher speed and thinner sheet of roll cast.
