ABSTRACT

Visualization and data analysis are crucial in analyzing and understanding a turbulent-flow simulation of size 4,096&amp;#xB3; cells per time slice (68 billion cells) and 17 time slices (one trillion total cells). The visualization techniques used help scientists investigate the dynamics of intense events individually and as these events form clusters.
