A visualization enhancement method based on physical value characteristics of Monte Carlo particle transport simulation

Abstract

The invention discloses a visualization enhancement method based on Monte Carlo particle transport simulation physical value characteristics. The method comprises the following steps of carrying out differentiation characteristic visualization different from grids where other physical values are positioned on the minimum value and the maximum value of physical values in a Monte Carlo particle transport simulation result to realize the visualization enhancement on the grids where extreme values are positioned; setting the transparency of the grid where a calculation error interval is positioned and which is appointed by a user to be 0 according to calculation errors in all grids in the Monte Carlo particle transport simulation result, and setting the transparency of the grid beyond the interval to be 1 to realize virtual enhancement on the calculation grid result of the appointed error interval. The visualization enhancement method can help the user to quickly position calculation grid areas concerned in neutronics analysis, so that the efficiency of the neutronics analysis is promoted.

Description

technical field [0001] The invention belongs to the field of neutronics analysis, in particular to post-processing and visualization of particle transport simulation results in neutronics analysis. Background technique [0002] In the physical design of reactors, fuel management optimization, environmental monitoring and radiation shielding research, nuclear safety analysis and other fields, neutronics calculation is an essential and important analysis method. Today, with the continuous improvement of computer processing capabilities, the data of neutronics calculation results are increasingly large and complex, and the post-processing of neutronics calculations has gradually become the bottleneck of neutronics analysis. As one of the most effective methods to analyze massive data, visualization technology will also play an important role in neutronics analysis. [0003] Since the concept of scientific computing visualization was formally proposed in 1987, after 30 years of...
