70 -- FINITE ELEMENT PRE- AND POST-PROCESSING SOFTWARE SOL 52SBNB5C8799 DUE 081595 POC Marsha Rodgers (301) 975-6339/Contracting Officer: Ruth Ann Maris The National Institute of Standards and Technology (NIST) has a requirement for finite element pre- and post-processing software with built-in solid modeler and an integrated interface to NIST flow modeling software. A software package and services are sought which enables the interfacing of an existing user-developed finite element flow modeling program with pre- and post-processing software which generates finite element meshes and displays finite element results. The software package to be acquired shall be an existing, interactive color graphics program for aiding finite element analysis being carried out on Silicon Graphics and other Unix/X/Motif based systems. The software shall provide mouse-driven rotation, pan and zoom of geometry, mesh and results models, with hidden line removal and the option of either flat or light shaded viewing. The software shall provide the ability to all custom interfaces to the existing package for interfacing with independent, user-developed finite element simulations. The pre-processing software shall provide: tools for advanced CAD geometry construction and manipulation; the ability to generate 1-D, 2-D and 3-D, finite element meshes from geometry data (auto-generation tools a plus); built in mesh optimization tools (e.g., node and element renumbering); read/write of common ''neutral'' CAD/CAE files formats which can be used as input into an independent, user-developed finite element code. Minimum requirements are for IGES geometry data, and NASTRAN finite element mesh and connectivity data. The post-processing software shall provide: display of steady and unsteady 2-D and 3-D field variable contour data (2-D color band and level lines, 3-D iso-surfaces) with a geometry sectioning option (for 3-D results), and auto-stepping through multi-time step contour data (animation); 2-D graphing/plot capabilities; the capability of displaying results from an independent, user developed finite element code through the use of neutral files. With the software, the vendor shall also provide an initial interface for interactive, graphical setting of material properties, fluid properties, and boundary conditions, and all other relevant information necessary to complete a simulation using an existing user-developed finite element flow modeling program along with the capability to launch and monitor the flow simulation, and view results when complete. The initial interface should also be user-customizable so that different properties, parameters, etc. can be added as the software changes-- F.O.B. Destination, Gaithersburg, Md--Required Delivery Time-- 45 days for delivery of software, 7 months for total integration. Evaluation Factors shall include the degree to which the proposal meets the specification, experience and capability, and Delivery Schedule and Product Quality--All responsible sources may submit a proposal which shall be considered by the agency--Please request copies of the solicitation in writing--Fax Number (301) 963-7732.
