Aim To visualize the explosive field and design a useful and practicable software tool to analyze explosive field. Methods An ideal model of the explosive field with a protective wall; which was simulated by another program MMIC(multi material in cell); was brought forward. The physical data output by MMIC were changed into image data represented by DIB bitmaps through the following steps: normalizing; coding; mapping and displaying. The object oriented method was applied in programming. Results and Conclusion With the tool; the explosive field with a protective wall is visualized. The overview of explosive field and some details about the transmission of shock wave in the field; such as reflection; flow over an obstacle and Mach reflection; are shown.
