Riemann Solvers and Numerical Methods for Fluid Dynamics,

这是一个基于abaqus二次开发的粘弹性边界模型，可以应用于abaqus地震计算的边界处理。(this is a secondary development of abaqus, it is about visco-elastic boundary and can be used for calculation for seism. )

应用背景ABAQUS的二次开发，通过umat实现邓肯张模型关键技术ABAQUS的二次开发，通过umat实现邓肯张本构，该模型考虑了土体的应力历史，压缩弹模与回弹弹模分别考虑，很好解决了abaqus计算土体方面的缺陷。

斯科特连接（由两相换成三相接线法）的实例，适用于PSCAD建模学习。(This case illustrates SCOTT connection.It s for learning about modeling in PSCAD.)

通过Fortran语言，利用牛顿方程迭代来求解非线性方程组，可设置为二元或多元(Through the Fortran language, the Newton equation iteration is used to solve the nonlinear equations, which can be set to two yuan or multivariate.)

Solver for linear ecuations system (SOR-successive over relaxation), very usefull!!.

金属材料的随动强化有限元模型，适用于有限元分析的本构模型二次开发(Finite element model of kinematic hardening of metallic materials, constitutive model suitable for finite element analysis of secondary development)

燃气轮机的设计资料，书后附有燃气轮机整机和各个部件的设计程序，在每个程序中给出了设计实例。(Gas turbine design information, the book with the machine and the various components of the gas turbine design process, design examples are given in each program.)

给定模型的层数以及每层的控制点，就可以得到所需模型。(Given the number of layers of the model and the control points of each layer, the desired model can be obtained.)
