D -- WAVE ANALYSIS MIT (WAMIT) COMPUTER SOFTWARE PACKAGE AND LICENSES POC Mallorie O. Irwin, Purchasing Agent, (601) 634-4116 WEB: Contracting Division Homepage, http://www.wes.army.mil/contract.htm. E-MAIL: Mallorie O. Irwin, irwin@exl.wes.army.mil. The USAE Waterways Experiment Station (WES) proposes to award a purchase order to the Massachusetts Institute of Technology, Technology Licensing Office, under authority of 10 U.S.C. 2304(c)(1) for the procurement of computer software package Wave Analysis MIT (WAMIT) for use in RIBS military project. The project will deploy a full scale version of the RIBS floating breakwater concept for research and development. WAMIT is a radiation/diffractin program intended for the analysis of the interaction of surface waves with floating structures. The WAMIT analysis software is required to properly optimize the design of the RIBS based on laboratory and field experiments. The WAMIT code is unique in all of the world for its capabilities and can only be obtained from the developer, Massachusetts Institute of Technology. The code has been thoroughly benchmarked for accuracy and is the industry standard. Characteristics of WAMIT: The formulation is based on a three-dimensional (3D) implementation of the panel method, and may handle arbitrary floating body geometry. The analysis is performed in the frequency domain, with the flow assumed to be ideal, time-harmonic, and with a linearized free-surface condition. An outstanding feature of the program is its capability to incorporate the structural deformations into the analysis. These deformations can be described by using a finite set of modal shapes that are added to the standard six degrees of freedom (DOF) of a floating rigid body. These generalized modes can also be used to describe multi-body configurations. Another feature of this program is the analysis of bodies which are not freely floating in waves. The 5.3 version is supplied in Fortran source code. The license agreement is for use on an unlimited number of machines at a single site. The foregoing described software is the only known software meeting WES requirements. No other sources will be sought. There is no solicitation document. Any inquiries should be received within fifteen days from the date of publication. (0344)
