70 -- ADINA STRUCTURES INTERACTION SOFTWARE POC Contract Specialist, Jack A. Little 601-634-3175 The U.S. Army Engineer Waterways Experiment Station (CEWES) proposes to award a contract to ADINA R&D, Inc., Watertown, MA, under authority of 40 U.S.C. 759(g), as amended, for ADINA Structures Interaction Software to be installed and operated on a CRAY C916. The contract will be awarded for a paid-up license to include product enhancements as they occur for a period of one year, with options to renew for two additional years. The Department of Defense (DOD) High Performance Computing Center at CEWES has a requirement for a finite element application that incorporates the abilities to analyze heat transfer, field, and fluid flow interaction with structures using both linear and nonlinear techniques. Required program features include: a. Displacement and stress analysis for solids and structures. b. A wide variety of material models including, but not limited to, soil, rocks, concrete, metals, plastics, rubber, wood, and ceramics. c. Linear and nonlinear techniques for both small and large deformations. d. The ability to handle contact problems with variable contact areas and friction. e. Automatic load stepping for static and dynamic analysis. f. Dynamic response, frequencies, or response spectrum analysis. g. Analysis of heat transfer, seepage, field and fluid flow in structures and field problems. h. Two and three dimensional, compressible and incompressible, viscous fluid flow with the ability to compute both laminar and turbulent flow regimes. i. Fracture Mechanics with crack propagation. j. Graphical pre-processor for the generation, plotting, and checking of meshes. k. Graphical post-processor for analysis of results. The software must run on a CRAY C916/161024 supercomputer located at the CEWES, Vicksburg, MS. The software must be supported by the UNICOS operating system version 8.0 and later. The delivered software's internal solution algorithms must be specifically optimized for maximum performance on the CRAY C916 system. The delivered software shall be compiled on a CRAY C916 system with current production versions of the UNICOS operating system and any required libraries. The software shall, at user-selectable option, permit the concurrent/parallel use of any number of C916 processors (up to 16) to be used in the solution of a single problem. The software will be made available for unlimited usage to any authorized DoD user, including those who access the system from remote locations. The foregoing described software is the only known commercial software directly compatible with DOD requirements. Any inquiries should be received within 15 days from the date of this publication. Solicitation documents are not available. (0100)
