【 摘 要 】

The analysis of extremely large data sets is time-consuming and tedious. In this project, we create two tools, the Image Inspector and the Video Inspector, to aid in the automated analysis of 3D temporal data from simulations. Our problem is the 3-dimensional time varying data of the Rayleigh-Taylor instability in a fluid mix problem. We examine the bubble dynamics due to the acceleration of gravity in an initially perturbed interface between a heavier and lighter fluid. Through the use of OpenGL and C++, we automate the capture of the temporal dependence of selected features along a chosen path in a time-dependent 3D simulation. The selected feature, e.g., the height of a bubble, is displayed graphically as a function of position and time. The path can be chosen arbitrarily; differing from previous projects which required the use of horizontal or vertical orientation.
