Based On Multi-fluid Grid Method Of Visual Computing Technology Research And Software Development,

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.
