Fiberbundle-Based Visualization of a Stirred-Tank Flow

Abstract

We describe a novel approach to treat data from a complex numerical simulation in a unified environment using a generic data model for scientific visualization. The model is constructed out of building blocks in a hierarchical scheme of seven levels, out of which only three are exposed to the end-user. This generic scheme allows for a wide variety of input formats, and results in powerful capabilities to connect data. We review the theory of this data model, implementation aspects in our visualization environment, and its application to computational fluid dynamic simulation of flow in an impeller-stirred tank. The computational data are given as a velocity vector field and a scalar pressure field on a mesh consisting of 2088 blocks in curvilinear coordinates.
