Abstract

Chimera Grid Tools (CGT) is a software package containing various modules for pre- and post-processing of computational simulations using overset grids. Most of the talk will focus on the new features introduced in version 2.2 released in June of 2018. Main topics will include a geometry interface via the Engineering Sketch Pad (ESP) open source library, various diagnostics for grid and domain connectivity quality, a library for automatic type and attributes detection for file I/O, a general cut-plane tool for grid and solution visualization, enhancements to the Script Library, and a script development tutorial for the steps in an overset CFD analysis process.

William Chan is a research scientist in the Computational Aerosciences Branch of the NASA Advanced Supercomputing Division at NASA Ames Research Center. His primary interest is on the development of algorithm and software for pre-processing and post-processing of computational simulations using overset grids. He is the principal developer of many of the modules in the Chimera Grid Tools (CGT) software package which has been distributed to over 900 organizations in U.S. government laboratories, industry and universities. Since joining NASA Ames, he has supported numerous NASA projects. These include high fidelity CFD simulations of the Space Shuttle Launch Vehicle, multiple subsonic, supersonic, and rotory-wing vehicles, various turbopumps and liquid rocket sub-systems, and a variety of space launch vehicles from the Constellation and Space Launch Systems Programs. His work has been recognized through the NASA Exceptional Achievement and Exceptional Service Medals, and various Technology Transfer awards. William obtained his B.S. in Mathematics from Southampton University in the U.K., and M.S. and Ph.D. from the Mechanical Engineering Department of Stanford University.
