AFLR has been under development for the last 25 years at the NSF/ERC center at Mississippi State University. The parallel procedure that is presented is called Pseudo-constrained (PsC) Parallel Data Refinement (PDR) and consists of the following steps: (i) use an octree datadecomposition scheme to divide the original geometry into subdomains (octree leaves), (ii) refine each subdomain with the proper adjustments of its neighbors using the given refinement code, and (iii) combine all subdomain data into a single, conforming mesh. Parallelism was achieved by implementing...

AFLR has been under development for the last 25 years at the NSF/ERC center at Mississippi State University. AFLR is currently used at NASA (including NASA/LaRC) and other government agencies as well as in the aerospace industry such as Boeing. The parallel procedure that is presented is called Parallel Data Refinement (PDR) and consists of the following steps: (i) use an octree data-decomposition scheme to break the original geometry into subdomains (octree leaves), (ii) refine each subdomain with the proper adjustments of its neighbors using the given refinement code, and (iii) combine all subdomain data into a single, conforming mesh. AFLR is shown to maintain weak reproducibility (i.e., able to produce results of the same quality when executed recurrently using the same input) as required...

The goal of my research project is to improve upon the current Imageto-Mesh Conversion tool (I2MTool) created by the Center for Real-Time Computing (CRTC). The I2MTool could be proven beneficial in a spectrum of disciplines that spans from Multiscale Materials and Structures Modeling to Finite Element (FE) analysis for NASA’s Computational Fluid Dynamics (CFD) 2030 Vision and Vision 2040 for Integrated Computational Structures Modeling. My project involves the development of visualization techniques to make models in simulations look more realistically, impacting research in nuclear physics, aeronautic simulations and health care applications. In this paper, I will present recent work on the CBC3D Slicer extension and the I2Mtool. CBC3D is one of CRTC’s 3D image-driven grid generation software that can generate high quality tetrahedral meshes. CBC3D was implemented as an extension within the...
