Interactive Feature Specification for Simulation Data on Time-Varying Grids.

Abstract

SimVis is an interactive research implementation of a visual analysis scheme which we developed for the feature-based assessment of flow simulation data. It is based on the concept of multiple, linked views of different kinds, including views from information visualization such as adapted scatterplots and histograms. In this paper we present an extension to our interactive visual analysis framework, which allows to handle data resulting from CFD simulations which are based on timevarying grids. For interactive and efficient handling of such large data sets, several optimizations had to be realized in the system. Furthermore, we demonstrate the application of our visualization approach in the context of an industry-level application, namely the visual analysis of CFD data from the simulation of combustion in a specific diesel engine. Here we especially focus on the description of how researchers and engineers use the SimVis approach to successfully investigate concrete user questions. 1
