Abstract

JMSI Inc d.b.a. Intelligent Light has completed Phase I SBIR research supporting the development of a new generalized high order Scientific and Engineering Data Analysis and Visualization (SEDAV) software tool based upon MFEM, a finite element library from Lawrence Livermore National Laboratory (LLNL). MFEM is currently used by the LLNL solver code, BLAST, for reactive flow simulations and also by LLNL’s SEDAV software VisIt. This new offering, named FieldView-HO, utilizes high order (HO) finite elements (FEM) integrated throughout the visualization/analysis pipeline to give scientists and engineers a tool to visualize and analyze their high order FEM based CFD results and grids with greater ease, interactivity and accuracy. By the completion of the Phase II SBIR project, JMSI will have developed a prototype SEDAV software that supports FEM based HO methods of any order, of any algorithm type (Discrete Galerkin, Continuous Galerkin, etc) and allows the user to interactively analyze and explore their high order based results using either in situ or post hoc methodologies. In our Phase I SBIR research, we studied how to move higher order elements through the visualization pipeline instead of up-sampled linearized elements with minimal added complexity to VisIt pipeline and how to accurately visualize themore »« less

''A Parallel Adaptive Simulation Tool for Two Phase Steady State Reacting Flows in Industrial Boilers and Furnaces''

Technical Report Michael J. Bockelie

This DOE SBIR Phase II final report summarizes research that has been performed to develop a parallel adaptive tool for modeling steady, two phase turbulent reacting flow. The target applications for the new tool are full scale, fossil-fuel fired boilers and furnaces such as those used in the electric utility industry, chemical process industry and mineral/metal process industry. The type of analyses to be performed on these systems are engineering calculations to evaluate the impact on overall furnace performance due to operational, process or equipment changes. To develop a Computational Fluid Dynamics (CFD) model of an industrial scale furnace requiresmore »« less
An Efficient, Semi-implicit Pressure-based Scheme Employing a High-resolution Finitie Element Method for Simulating Transient and Steady, Inviscid and Viscous, Compressible Flows on Unstructured Grids

Technical Report Richard C. Martineau ; Ray A. Berry

A new semi-implicit pressure-based Computational Fluid Dynamics (CFD) scheme for simulating a wide range of transient and steady, inviscid and viscous compressible flow on unstructured finite elements is presented here. This new CFD scheme, termed the PCICEFEM (Pressure-Corrected ICE-Finite Element Method) scheme, is composed of three computational phases, an explicit predictor, an elliptic pressure Poisson solution, and a semiimplicit pressure-correction of the flow variables. The PCICE-FEM scheme is capable of second-order temporal accuracy by incorporating a combination of a time-weighted form of the two-step Taylor-Galerkin Finite Element Method scheme as an explicit predictor for the balance of momentum equations andmore »« less

Collaborative Visualization for Large-Scale Accelerator Electromagnetic Modeling (Final Report)

Technical Report William J. Schroeder

This report contains the comprehensive summary of the work performed on the SBIR Phase II, Collaborative Visualization for Large-Scale Accelerator Electromagnetic Modeling at Kitware Inc. in collaboration with Stanford Linear Accelerator Center (SLAC). The goal of the work was to develop collaborative visualization tools for large-scale data as illustrated in the figure below. The solutions we proposed address the typical problems faced by geographicallyand organizationally-separated research and engineering teams, who produce large data (either through simulation or experimental measurement) and wish to work together to analyze and understand their data. Because the data is large, we expect that it cannotmore »« less

In particular, the cloud app(s) proposed here addresses the problem of advancing current capabilities for designing next generation wind turbines andmore »« less
ViSUS: Visualization Streams for Ultimate Scalability

Technical Report Pascucci, V

In this project we developed a suite of progressive visualization algorithms and a data-streaming infrastructure that enable interactive exploration of scientific datasets of unprecedented size. The methodology aims to globally optimize the data flow in a pipeline of processing modules. Each module reads a multi-resolution representation of the input while producing a multi-resolution representation of the output. The use of multi-resolution representations provides the necessary flexibility to trade speed for accuracy in the visualization process. Maximum coherency and minimum delay in the data-flow is achieved by extensive use of progressive algorithms that continuously map local geometric updates of the inputmore »« less
