70 -- ENGINEERING ANALYSIS LANGUAGE (EAL) SOFTWARE SOL 8-P-6-16-92925 POC Contact GP22L/Janice M. Stewart,Contract Specialist, 205-544-6093 or GP22C/Teresa A. Foley, Contracting Officer NASA/MSFC plans to issue a Request for Quotation (RFQ) for Monthly Lease of Engineering Analysis Language (EAL) Software, Level 330 or higher, quantity--3 ea--11.01/95-10/31/96 unit cost + per user for 12 months--The following are the functional specs for Engineering Analysis Language (EAL) -- The code shall be able to construct structural models of arbitrary configuration using a variety of different element shapes: 1-D Beam elements; 2-D shell elements; laminated shells; five and six sided 3-D solid elements shall be included along with a formulation for fluid elements to model phenomena such as slosh and other hydroelastic dynamics The code shall be able to calculate static displacements and reaction forces for the aforementioned beam, plate, and solid elements -- The code shall be able to calculate the vibration eigenvalues of structural and fluid models -- A shifting capability must be included that allows a subset of modes to be isolated -- The code shall be able to compute the buckling modes of modeled structures -- The code shall be capable of system modification of a large number of requested parameters for use in model verification with modal tests -- The code shall be able to employ analysis procedures which make use of cyclic symmetry in the model to aid both in CPU time savings and model size -- The code shall be able to perform analysis using substructuring techniques such as macroelements and component mode synthesis in superelement analysis -- The code shall be able to perform modal transient response analysis with results in the form of displacements and/or stress -- The code shall be able to perform random response analysis by inputting a power spectral density (psd) spectrum and calculating a response psd spectrum of the structure -- The code shall have extensive mathematical capability which can be applied at any point during the problem solution -- The user shall be able to create and combine any scalar or matrix or set of scalars/matrices and perform all standard operations upon them -- Any arbitrary vector or array shall be able to be created to simulate loading conditions that vary in time and space - All matrices created by the code itself (e.g. mass and stiffness matrices) shall also be accessible for manipulation -- Conditional and incremental looping shall also be available when using the above capabilities -- The code shall be able to perform geometric and material nonlinear analysis. Ability to use gap elements is also required -- The code shall be able to provide graphic display of quantities such as element geometry, deformed modeshapes, and static displacement -- To aid in this area, some type of translator must exist to allow for results translation into PATRAN/P3 -- The code shall provide the capability for a straight forward conversion of the historical data base of analyses performed -- The code shall provide the capability for both finite element geometry and results to be read into and out of the CAD software PATRAN/P3 The code shall allow for independent evaluation of element accuracy and convergence by standardized finite element tests such as the MacNeal-Harder tests -- The code vendor shall furnish the following: multiple copies of documentation as needed, detailed functional and operational instruction of the code, relation of code operation to basic theory and engineering practices, and a thorough set of verification problems for code examination -- Verification and demonstration problems shall fully illustrate the extent of the code's capability -- The code vendor shall provide technical support and training for all users -- Also, the code vendor shall provide for growth capability to include additional capabilities to any ongoing current versions of the code as well as furnishing documentation of the changes as they occur -- NASA/MSFC intends to purchase from Engineering Information Systems Incorporated (EISI), Saratoga, California-- This procurement is being conducted under the Simplified Acquisition Threshold (SAT) portion of the Federal Acquisition Streamlining Act (FASA) -- Note: This procurement is sole-source based on proprietary specifications and system compatability requirements -- Interested firms have 15 days from the publication date of this synopsis to submit in writing their qualifications/capabilities in the critical areas mentioned above -- Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis -- Responses received after the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered -- A determination by the Government not to compete this proposed contract, on a full and open competitive basis, based upon responses to this notice, is solely within the discretion of the Government -- See Numbered Note 22 -- Oral communications are not acceptable in response to this notice -- Responses must be submitted in writing -- Transmission by facsimile to 205-544-9080 or by Internet e-mail to janice.stewart@msfc.nasa.gov is acceptable -- The solicitation and any related documents to this procurement will be available over the Internet -- These documents will be in ASCII format and reside on a World-Wide Web (WWW) server, which may be accessed using client browsers, such as, MOSAIC -- The WWW address, or URL, of the MSFC Procurement home page is: ''http://procure.msfc.nasa.gov''.
