Problems solved by technology

However, due to limitations such as program computer memory usage, the existing Monte Carlo visualization software system cannot render a large-scale fine fission reactor model at one time, or even if it can complete the rendering of a large-scale fine fission reactor model, the cost is very high The support of professional graphics workstations, and the speed of getting the complete model is also very slow, so that the Monte Carlo geometric model cannot be visualized or the cost is too high during the modeling process, or the display interaction speed is too slow to meet practical applications

Embodiment Construction

[0029] The present invention can quickly visualize a large-scale fission reactor model. After the user imports the three-dimensional CAD model or the Monte Carlo calculation model, the models are intelligently grouped, and some models are called for visualization according to the user's needs. At the same time, different models can be selected. The detailed program of visualization is implemented in the following ways:

[0030] The first step is to import the CAD model or Monte Carlo calculation model of each component through the software interface;

[0031] The second step is to build a hierarchical structure tree. If the Monte Carlo physical calculation model is imported, the direct assembly relationship and filling relationship of the model can be directly analyzed from it, and the parameters and lists of the half-space surfaces can be obtained. If it is an MCNP program The calculation model of the same component is assigned the same universe number, such as figure 1 As s...

Abstract

The invention relates to a multiscale fissioning core visualization method based on an automatic merging hierarchical structure tree. The visualization method is used in fission reactor design to check the correctness of the design of a reactor core which has been constructed or is being constructed. Based on the hierarchical feature of a fission reactor, a user input model is analyzed, grouping of a hiberarchy relation structure is established intelligently, a corresponding rendering unit is generated based on grouping, an overall rendering tree structure is established, and quick visualization of an area in which a user is interested is achieved; visualization speed is increased greatly, real-time visualization during modeling of a fine reactor core model is realized, and then fissioning core modeling efficiency is improved remarkably.

Description

technical field [0001] The invention relates to the technical field of rapid visualization of fission reactor models, in particular to a multi-scale fission reactor core visualization system based on automatic merging hierarchical structure trees. Background technique [0002] The key part of Monte Carlo calculation is the processing of geometry. The key to geometric processing is to ensure the geometric correctness of the calculation model. For this reason, it is necessary to complete the modeling during the process of Monte Carlo geometric modeling and the confirmation process before Monte Carlo calculation. The correctness of the Monte Carlo calculation model. Model visualization is the most intuitive and efficient way of inspection. In particular, in order to ensure modeling efficiency, the inspection during the modeling process requires interactive real-time observation. [0003] As Monte Carlo calculations are increasingly used in fission core design, users are deman...
