NASA's NAS Division researcher
Michael Aftosmis and colleague Marsha Berger, professor and deputy director of Courant Institute, New York University, have received the American Institute of Aeronautics and Astronautics (AIAA) best paper award for 2002.
Their paper, “Multilevel Error Estimation and Adaptive h-Refinement for Cartesian Meshes with Embedded Boundaries” describes the team’s development of new techniques for error estimation and adaptive refinement for computational fluid dynamics (CFD) solutions.
Several features put this new h-refinement strategy a cut above previous adaptive meshing techniques: “It is general enough that it can be applied to any type of unstructured or hierarchical mesh, and, since it is parameter-free, it can be fully automated,” explains Aftosmis. The new meshing strategy was also designated to remove the dependence on user skill, making it quick and easy to generate meshes.
Aftosmis and Berger plan to integrate these error estimation and refinement techniques into their grid generation and solution software package,
