A -- ENHANCEMENTS TO AN ADVANCED COUPLED CSD/CFD TOOL SOL DNA001-92-C-0158 POC Thomas L. Cox, Negotiator, (703) 325-1196, Scott G. Morton, Contracting Officer, (703) 325-1200. The objective of this contrat modification is to markedly enhance the Advanced Integrated CSD/CFD Analysis Tool. This is to develop a state-of-the-art Integrated Computational Structural Dynamics (CSD) and Computational Fluid Dynamics (CFD) tool. The tool enables analysis of complicated three dimensional (3-D) coupled CSD/CFD problems. The approach adopted by Science Applications International Corporation (SAIC) involve innovative techniques that prohibit other organizations from participation. Development/generation of three dimesional unstructured grids of arbitrary connectivity for both the fluid and the structure; adaptive refinement and flexible time-stepping applied to the fully coupled fluid and structure response. Contemplated period of performance is 26 months. The Defense Nuclear Agency (DNA) intends to award a sole source contract to SAIC for the above services on the basis that DNA has determined that only SAIC possesses the prerequisite knowledge and background for satisfactory performance. No copies of the solicitation are available. This synopsis is for information only. For information contact Thomas L. Cox at (703) 325-1196. Information on DNA solicitations, already released, can be obtained by calling the DNA Hotline at (703) 325-1173. Reference Synopsis No.95-53 (0138)
