针对手工编写MCNP输入文件中几何模块容易出错的问题,采用Spatial公司推出ACIS提供的API函数、C++类和DI函数3种开发接口,实现根据给定的CAD模型得到该模型中所有曲面的面方程,在曲面与坐标轴不平行时,以辅助坐标系的形式简化面方程,最终自动生成MCNP格式的曲面卡.通过对不同模型的验证,该方法可以正确生成曲面卡,能提高编写MCNP输入文件的效率.

Since the geometry module in hand?written MCNP input file is easy to make mistakes,three development inter?faces(API function,C++ class and direct interface function)provided by Spatial Company’s ACIS were adopted to get the sur?face equation for all surfaces in the model according to the given CAD model. Especially when the uneven surface and coordi?nate axis line is not parallel,the simplified surface equation of the auxiliary coordinate system is used to automatically generate the curved surface card with MCNP format. Through validation of different models,this method can generate the surface card correctly and improve the efficiency of compiling the MCNP input file.
