Development of a geometry-coupled visual analysis system for MCNP

MCNP is a general and powerful Monte Carlo code for photons, neutrons, and electrons transport simulation and is widely used in nuclear analysis. However, external specialized data analysis codes may be needed to analyze complex MCNP calculation results. Especially, there is a lack of efficient data analysis codes which supports geometry-coupled visual analysis. To address the post-processing concerns, a geometry-coupled visual analysis system for MCNP, was developed with 3D scientific visualization and graphics processing unit programming technologies by FDS Team. It was designed and implemented to provide friendly graphical user interface based data manipulation, 3D plotting of tally results, and visual data analysis coupled with geometries. Testing and preliminary application results showed that the system provided a satisfied visual analysis approach for the post-processing of MCNP and obviously enhanced the analysis efficiency.
