Pulmonary embolism (PE) is a significant medical problem that results in over 300,000 fatalities per year. A common preventative treatment for PE is the insertion of a metallic filter into the inferior vena cava that traps thrombi before they reach the lungs. The goal of this work is to use methods of mathematical modeling and design optimization to… (More)

We discuss an interactive environment for the visualization, analysis, and modiication of computational models used in industrial settings. In particular, we focus on interactively placing massless, massed, and evaporating particulate matter in computational uid dynamics applications. We discuss the numerical model used to compute the particle pathlines in… (More)

In this paper we describe an interactive virtual environment developed to model an emission reduction system for commercial boilers. The interactive environment is used to optimize the performance of the reduction system through the spatial adjustment and spray reconngura-tion of reagent injectors. We describe the three principal components of the system: a… (More)

Analytic solutions for streamlines within tetra-hedra are used to deene operators that accurately and eeciently compute streamlines. The method presented here is based on linear interpolation, and therefore produces exact results for linear velocity elds. In addition, the method requires less computation than the forward Euler numerical method. Results are… (More)

Most software packages available for particle tracing focus on visualizing steady or unsteady vector elds by using massless particle trajectories. For many applications, however, the use of massed and evaporating particles would provide a model of physical processes that could be used in product testing or design. In this article we describe the TrackPack… (More)
