- Description
- NASA/LaRC has a requirement for Mesh adaptation software that may be coupled with two NASA unstructured Computational Fluid Dynamics (CFD) codes, FUN3D and USM3D. Mesh adaptation will enhance the accuracy of CFD solutions in a number of critical areas of interest to NASA, in particular to the prediction of aerodynamic loads on the ARES vehicle (Crew Launch Vehicle) under evaluation by the Exploration Systems Mission Directorate. The software should be able to read the solution files for both FUN3D and USM3D. Then, adapt the grid, interpolate the solution based on user defined parameters and provide solution files that are compatible with both USM3D and FUN3D format. Because of the large problem sizes being run for ARES, the adaptation must be done able to be performed on multiple processors; single-processor adaptation will place an unacceptable bottleneck in the solution process. While USM3D and FUN3D both use tetrahedral elements, FUN3D can also use hexahedral and prismatic elements, so the mesh adaptation software must also be able to handle these element types. In addition, the file formats used by USM3D and FUN3D differ and must be accommodated by the mesh adaptation software. NASA/LaRC intends to purchase the services from. Combustion Research And Flow Technology (Craft Tech), who is the only known responsible source. The CRAFT Tech CRISP code is currently compatible with USM3D, and can be modified to provide compatibility with FUN3D; the CRISP software performs dynamic load balancing in addition to parallel adaptation, resulting in more efficient use of available computational resources; and offers a choice of feature-based or error-based adaptation. The sole source authority for this item is FAR 13.106-1(b)(1). The Government intends to acquire a commercial item using FAR Part 12. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on September 20, 2006. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
