In chapter 4 , we present some new techniques in designing finite difference domain decomposition algorithm for the heat equation . the basic procedure is to define the finite difference schemes at the interface grid points with smaller time step by explicit schemes , and the prior error estimates for the numerical solutions are obtained 在第四章,我們發(fā)展了一些新技術(shù),在子區(qū)域的邊界處采用小時間步長古典顯式格式求解,構(gòu)造了新的區(qū)域分解算法,得到了差分解的先驗誤差估計。
In this paper the basic principle of the method of characteristics is described , and is constructed an explicit scheme for dam break simulation of one - dimensional dam instant all break waves flow of a low dam with rectangle section and a huge dam with trapezia section , and of two - dimensional dam instant part break waves flow with simplest space operator splitting 本文模擬了一維矩形斷面低壩和梯形斷面巨型壩瞬間全潰的洪水波演進過程,給出了與分析解的比較,并結(jié)合算子分裂的特征線法對二維瞬間部分潰壩時洪水波的演進過程進行了數(shù)值模擬。
A complex mixed - phase explicit microphysical parameterization scheme , which also be known as reisner 2 explicit scheme was developed for use in the ncar / penn state mesoscale model versions ( mm5 ) . the single - moment schemes has additional variables for graupel and ice number concentration , in which the mixing ratio of cloud water , rain water , cloud ice , snow and graupel are predicted and number concentration specified Mm5中的reisner2方案是一種含霰的復(fù)雜混合相顯式云物理方案,該方案包含了云水、雨水、冰晶、雪和霰的混合比預(yù)報方程,同時對冰晶的數(shù)濃度作了預(yù)報。
