摘要
MCAM(MCNP Automatic Modeling)是自主开发的MCNP(Monte Carlo Neutral Particle)辅助建模软件。讨论了该软件中的优化技术。BREP→CSG转换算法是MCAM的核心算法,借助三维特征识别技术能改进该转换算法。讨论了在MCAM中引入特征识别技术的必要性和可能性,并介绍了MCAM中基于“转换特征”的改进BREP→CSG转换算法及其效果。
MCAM （MCNP Automatic Modeling） is a computer aided modeling tool of MCNP （Monte Carlo Neutral Particle） with our own copyright. The optimization technology within this software is discussed. The BREP→CSG conversion algorithm is the core in MCAM, and it is possible to improve the algorithm using 3D feature recognition technology. The paper discusses the necessity and possibility of introducing 3D feature recognition technology and introduces the improved BREP→CSG conversion algorithm based on ＂feature conversion＂. The effect of the algorithm is described as well.
