abaqus 插件，用于生成晶粒. 将其放在abaqus_plugins文件夹中即可使用。(The file is an abaqus plugin which is used to generate grain in the abaqus. It is available when put into the abaqus_plugins files.)

根据输入不同的晶粒数，生成VT图形，可二次开发(According to the different number of grains, VT graphics can be generated, which can be developed two times.)

程序首先读取MATLAB生成的三维晶粒点数据，然后在ABAQUS中实现3D 晶粒建模(3D grain modeling in ABAQUS)
