2. SUPPORTING DOCUMENTATION FOR BRAND NAME BASED ON

CONTRACTOR’S UNIQUE QUALIFICATIONS OR NATURE OF THE

ACQUISITION

The software package NX Mach 3 Product Design and its add-ons part of the Siemens PLM

(Product Life-Cycle Management) family of software products will be installed on RDT&E assets in the Maritime Systems Hydromechanics Branch (Code 881) who are working alongside

NUWC Newport, NSWC Panama City, NUWC Keyport, and Penn State /ARL on developing the

Navy’s prototype LDUUV. This software will be used to design and analyze the Flooded Nose

Section (FNS) and launch and recovery towed body. NX provides Carderock and its team members the ability to design and exchange complex 3D geometries and drawings in their native format. In addition, the Simcenter 3D add-on allows the initial designers the ability to evaluate their designs structurally all within the same session of NX reducing the need to export models to third party solvers.

NUWC Newport is the Lead System Integrator for the LDUUV program and uses NX for their design. Having the ability to interface directly with NUWC in the native NX format is essential as our designs increase in complexity. Transferring information in the native design tool’s format preserves its feature tree, material properties, version information, appearance detail, and the most essential feature of all, the ability to automatically update the linked drawing when a 3D model has changed. For instance, if we were to design in any other CAD software NUWC

Enclosure (1) would need to recreate the part in NX which doubles government time and reduces NUWC’s manpower effectiveness if someone is just recreating something we have already done.

The Simcenter 3D add-on is also an essential tool for our designers to have. Simcenter 3D uses an industry recognized solver called NASTRAN to perform linear and nonlinear finite element analysis. Just like the mechanical design features of NX, Simcenter 3D add-on will allow for

Carderock and its team members to share files in their native format reducing the need for rework and program translation risk. Performing the analysis with the same solver also allows others to check the analysis easier and get the same results. If another more complex solver is needed Simcenter 3D can export a mesh of the part that is widely recognized as an input, reducing the usually time intensive process of model clean up.

Configuration Management (CM) is a requirement that NUWC and its partners need to use during critical design and manufacturing. NUWC has chosen to implement Teamcenter which is a NX add-on for its version control of 3D models and drawings. It’s essential for Carderock to comply with this requirement and since its part of the Siemens PLM software package there will be no additional software needed to integrate with NX.

Learning Advantage Gold Membership is Siemens PLM software online training portal. The

Code 881 team requires access to this online training to be able to effectively use the Siemens

PLM software package.

3. MARKET SURVEY

Various CAD programs were evaluated as a potential solution, but none of them would allow for native file translation and configuration management. Similarly, Simcenter Structures uses an industry trusted finite element solver integrated into NX which increases the accuracy of our initial design and reduces rework. The supplies and services are on GSA schedule 70.

4. ADDITIONAL FACTS

Siemens has exclusive rights to provide upgrades for this software since they have the copyright and continue to upgrade and improve it.
