1. DESCRIPTION OF REQUIRED SUPPLIES/SERVICES, ESTIMATED

VALUE, AND DELIVERY REQUIREMENTS

Code 65 is required to renew its annual Maintenance for FEMAP, FEMAP w/NX NASTRAN and NX NASTRAN Licenses. FEMAP is a finite element modeling and post-processing environment that builds a model and then translates the information into code to be passed to a solver. NX NASTRAN is a separate solver product that is usually bundled within FEMAP and is one of the most common solvers for finite element analysis (FEA). NX NASTRAN computes the behavior of the model, and then FEMAP imports those results, allowing Code 65 to query the resultant vectors and view deformations and contours.

Annual maintenance gives Code 65 the ability to support advanced ship structural design and analysis by providing access to software technical support and new version releases.

The estimated cost of the software package is . The Period of Performance for NSWCCD’s Install ID #1196545 is 07/01/19 to 06/30/20.

The following additional fees could apply if not awarded by the completion date.

2. SUPPORTING DOCUMENTATION FOR BRAND NAME BASED ON

CONTRACTOR’S UNIQUE QUALIFICATIONS OR NATURE OF THE

ACQUISITION

Advanced structural analysis and optimization of Navy ship and submarine structures requires advanced computational software. FEMAP provides advanced modeling, pre-processing, meshing, and post-processing required to support advanced ship structural analysis and the flexibility and robustness required to interface with a large number of commercial design applications. Analysis capabilities include full ship modeling, local structural analysis, and optimization with structural degradation. NX NASTRAN supports large ship structural modeling using beam elements integrated with shell elements. The structural analysis capabilities allow efficient modal analysis and linear seaway load analysis of these structures.

While there are many FE modeling programs, they each have their own advantages and pitfalls. Code 65 has a small number of licenses of other software to be used in specific situations, and occasionally tests out a new program, but FEMAP/NASTRAN is consistently found to best suit their needs.

NX NASTRAN has been validated and verified by the Navy to perform FEA. FEMAP, specifically, is required for access to legacy models, and has the ability to interact with the various (sometimes proprietary) software of private sector vendors, shipbuilders, and design firms that provide support. This means vendors are not restricted in their choice of software.

Code 65 has been using FEMAP with Nastran for over 20 years, and all 31 licenses are used regularly. Switching to another software would require significant time and money be spent on training the workforce (low estimate: 40 people for two weeks of training

, updating legacy models, and validating the results. Some data would be lost, and time-sensitive tasks would be adversely affected. In addition, initial installations are usually much more expensive than annual maintenance fees, which would be a large up-front cost.

Siemens Product Lifecycle Management (PLM) Software Incorporated is the sole developer of FEMAP with NX Nastran software package.

The impact of not completing the FEMAP renewal procurement would mean a loss of mission capabilities. When the software license period ends, so do software updates and support necessary to maintain the capability to work with contractors supplying FEA models using the latest version of the code. With the software no longer functioning, all projects will have to delay or stop work until the software purchase has been made.

3. MARKET SURVEY

A market survey was conducted and determined that, even though this software is available on the commercial market, Saratech has been assigned by Siemens PLM Software as the designated partner to support NSWC Carderock Install ID# 1196545.

FEMAP/NASTRAN is available on NASA SEWP from several authorized small business resellers (they buy it from Siemens who then assigns Saratech to provide the maintenance). Spatial Integrated Systems (SiS) also sells Siemens Products via the GSA

Advantage website, however, not all of the products in this procurement are directly available on the GSA Advantage website.
