Ensemble simulation can be used to examine aleatoric uncertainty in simulation models that contain stochastic effects. For this purpose, a simulation experiment is performed many times to generate an ensemble of realizations of the model. The object of the 2016 Scientific Visualization Contest is the visualization of an ensemble of three-dimensional, transient fluid flows obtained through particle simulation with stochastic effects at multiple levels of resolution.
In this ensemble, the behavior of so-called viscous fingers is of primary interest. The six-dimensional nature and size of the data is the main challenge for visualization. Effective browsing, summarization, and data reduction strategies are needed to obtain meaningful insight into the data.
