VICKSBURG, Miss.--Department of Defense’s (DOD) High Performance Computing Modernization Program (HPCMP) employees located at ERDC’s Information Technology Laboratory (ITL) were recently selected to receive the American Institute of Aeronautics and Astronautics (AIAA) 2012 Shahyar Pirzadeh Memorial Award for Outstanding Paper.
The AIAA’s Meshing Visualization and Computational Environments technical committee selected Sean Kamar and Andy Wissink to receive the 2012 AIAA Shahyar Pirzadeh Memorial Award for Outstanding Paper for "An Automated Adaptive Mesh Refinement Scheme for Unsteady Aerodynamic Wakes."
Kamar is a postdoctoral student and Wissink is the lead code architect of the Computational Research and Engineering Acquisition Tools and Environments Helios project in the DOD HPCMP.
The paper described methods they developed and used to determine the optimum level of adaptive mesh refinement without user intervention for unsteady vortex flows in rotorcraft simulations. The technique greatly improves the ability of Helios to predict the performance of advanced rotorcraft.
The award was named in memory of a valued contributor to the field of unstructured numerical mesh generation. Pirzadeh, who passed away in 2009, was best known for his work with the VGRID unstructured mesh generator. His many innovations included the advancing layers method and early adoption of the Cartesian background grid to control mesh spacing.
