MCNP可视化输入程序的开发

Development of visualized input for MCNP

MCNP(Monte Carlo N-particle)输入文件格式较复杂,特别是对相关物体几何参数的描写更难,不仅书写麻烦,而且很容易出错。为方便用户准确得到输入文件,进行了MCNP可视化输入程序的开发。程序运行于Windows平台下,使用VC++和OpenGL语言编译。应用该程序,用户能够在一个三维可视化环境中创建几何体并定义区域,描写数据卡,最后直接得到符合MCNP输入文件格式要求的inp文件。

The format of MCNP input files is very complicated,especially the geometric descriptions of the objects.Writing of the input file is not only difficult,but often results in errors.A program was developed for Windows platforms to automatically generate input files.The program was compiled with VC++ and OpenGL languages.This program can construct three-dimensional geometric entities,visualize regions,describe the data cards,and generate the input file with the MCNP input file format directly,so the user can more easily use the MCNP.
