计算爆炸力学 meaning in English
computation explosion mechanics
Examples
- Computation explosion mechanics
计算爆炸力学 - In this paper , the concepts , the historical background , the importance and current application of scientific computing and visualization of scientific computing are introduced and the visualization of computational detonation mechanics is specially expounded . based on the sumarization of the visualization software visc2d and visc3d directing at the mmic ( multi _ material in cell ) , the key point of the improvement and the research contents are listed . based on the basic visualization reference model and the data file format of mmic , the file format of vector data is defined . the 2 - d data field visualization technology is described in detail . include the visualization of scalar field and vector field . the weak points of the visc2d software is overcome , and we propose the full - frame coloring mapping method and the visualization of the vector data using the clic ( coloring _ noise line integral convolution ) . in addition , the method to draw and display shock wave by edge probing operator is introduced . in the design of the program , in order to overcome the shortcoming of visc2d with sdi ( single document interface ) , the software vsv ( visualization of scalar and vector ) with mdi ( multi document interface ) is designed . compared with visc2d , the advantage of vsv includes : ( l ) vsv is a mdi applied software which can be used to view various kind of data , ( 2 ) vsv resolves the flash during displaying moving images which are produed by full - frame coloring method used to the visualization of scalar fields , and ( 3 ) vsv can be used to visualize vector field such as velocity . at last , the visualization of the output data from mmic in explosion and shock is realized by vsv
首先简要介绍了科学计算与科学计算可视化的概念、历史背景、意义及应用现状，重点说明了计算爆炸力学中的可视化问题，在总结多流体网格程序mmic的可视化软件visc2d和visc3d的基础上提出了改进要点和本文的研究内容。在介绍可视化基本参考模型和mmic程序的数据文件结构的基础上，给出了矢量数据文件的结构，详细阐述了二维数据场的可视化技术，包括标量场和矢量场的可视化，针对原visc2d软件的不足，给出了改进方法，提出了全帧着色映射方法和用于矢量数据可视化的基于噪声着色的线积分卷积方法，以及提出了利用边缘检测算子提取和显示冲击波的方法。在程序设计上，针对原visc2d软件只适用于单文档窗口的缺点，本文利用多文档mdi窗口，研制了标量场与矢量场的可视化软件vsv ( visualizationofscalarandvector ) 。
