摘　　要：蒙特卡罗粒子输运程序MCNP在分析复杂例题的模拟计算结果数据时,具有分析过程不直观、效率低等问题。FDS团队结合科学计算可视化技术、GPU(图形处理器)可视化编程技术,以及本团队自动建模系统MCAM的反向转换引擎,自主研发了集数据分类提取、图形化管理以及结合几何的三维数据可视化分析功能于一体的MCNP计算结果可视化分析系统。以国际热核实验堆ITER为代表的大量测试结果表明,该系统显著提高了数据的利用率和分析效率。The post-processing capability of the current MCNP is not enough to effectively and sufficiently analyze calculation results of complex problems.In the paper,a geometry coupled visual analysis system for MCNP was self-developed in FDS Team by using scientific visualization technology,GPU（graphics processing unit）visual programming technology,and the reversion engine of MCAM.The visual analysis system was implemented to support data extraction and manipulation based on graphics user interface,three-dimensional plotting of tally results,and visual analysis of the results with geometries.And the system has been tested by many de facto cases,such as ITER.Testing results showed that the system provided an intuitively and effectively visual analysis approach for the post-processing of MCNP and obviously enhanced the analysis efficiency.
