Title: Phase I SBIR Final Report- FieldView-HO: a generalized high order FEM framework for engineering CFD in situ and post hoc data analysis and visualization

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 » curvature inherent to high order elements. The new methods were demonstrated by visualizing grid and results data in both FieldView and VisIt using realistic HO-FEM grid data from a commercial grid generation package, Pointwise, and results data from a Computational Fluid Dynamics (CFD) solver, COFFE, from the University of Tennessee-Knoxville.« less
