Integrated Overset Meshing and Grid Assembly Capability

ABSTRACT: Pointwise, Inc. proposes to integrate overset grid assembly (OGA) software with its state-of-the-art mesh generation software to allow efficient, effective overset meshing and grid assembly. Support for structured and unstructured overset meshing will be added. Composite mesh visualization tools will be added to aid the user in locating, understanding, and correcting overset assembly problems. OGA data input will be refined to handle definition of complex configurations, including support for dynamic moving body problems encountered in defense-related simulations. Research into automated meshing methods for improved overset meshing will be conducted. Two new meshing features utilizing OGA results to automatically improve overset communication will be implemented. Additionally, a state-of-the-art overset grid assembly execution system applicable to high performance computing hardware, will be developed. BENEFIT: It is anticipated that by integrating meshing software with overset grid assembly software and automating overset mesh remediation, manpower required for CFD pre-processing of complex configurations could be reduced by as much as 50%. Such a product would be directly applicable to computational analysis of complex configurations of all types, especially those involving moving-body aerodynamics.
