abaqus自带Umat

是一款对ABAQUS的二次补充开发的模型软件，开发步骤和内容在本文中详细给出，供大家参考(Is a model of added secondary development of ABAQUS software, development steps and content is given in detail in this paper, for your reference)

基于笛卡尔网格的自适应网格生成，实现方式相对简单，灵活易用。(PARAMESH is a package of Fortran 90 subroutines designed to provide an application developer with an easy route to extend an existing serial code which uses a logically cartesian structured mesh into a parallel code with adaptive mesh refinement(AMR).)

定量遥感中需要的球形粒子散射（mie）计算源码(mie computing source code for spherical particles)

说明：  在abaqus中可用于自定义的粘弹性材料模型，材料模型采用的是三参量固体模型，可通过输入粘性参量和弹性参量定义材料的参数。(be used for some materials with the viscoelastic property)

采用相场方法，计算纯物质枝晶生长，标记为相场模型C。(Dendrite growth of pure substance was calculated by phase field method, marked as phase field model C.)

采用Fortran编写的二维非线性有限元计算程序，内有程序变量说明，可用于计算弯曲梁的大变形(Fortran prepared using a two-dimensional nonlinear finite element program variables within a program description can be used to calculate the bending beam of the large deformation)

利用简正波理论来计算声场，其中用到的思想可以在《计算海洋声学》中找到(using the nomal mode theary to compute the sound field)

Fortran语言解决一维激波管问题，本程序为一阶迎风Roe格式(Fortran language to solve one-dimensional shock tube problem, this program is the first order upwind Roe format)

用于ABAQUS二次开发，考虑温度和应变速率的热动力学程序。是用于隐式算法的umat文件(a Fortran code for thermoviscoplastic algorithm. implicit algorithm for abaqus umat)

运用格子Boltzmann方法中的伪势模型，模拟胀大平面流道中的两相流动，左边幂律流，右边牛顿流体。得出流动过程中，各个瞬态的结果。(Using lattice Boltzmann method of pseudo potential model to simulate the swell plane channel flow, on the left side of the power-law fluid flow. On the right side of the Newtonian fluid. In the process of flowing, the result of each transient.)
