NSWCCD Sole Source/Brand Name Justification Under SAT Rev 4 Template Page 1 of 4 Effective February 2024

MEMORANDUM FOR FILE

FROM: Susan Brewton CODE: Code 871 TO: Code 02 SUBJECT: Sole Source/Brand Name Justification / Limited Source Justification for Use of Other than Full &

Open Competition for an Acquisition under the Simplified Acquisition Threshold (SAT)

I. BACKGROUND

1. FAR 13.106-1(b)(1)(i) states for purchases not exceeding the simplified acquisition threshold, Contracting Officers may solicit from one source if the Contracting Officer determines that the circumstances of the contract action deem only one source reasonably available.

2. FAR 8.405-6(b)(1) states Brand name specifications shall not be used unless the particular brand name, product, or feature is essential to the Government’s requirements, and market research indicates other companies’ similar products, or products lacking the particular feature, do not meet, or cannot be modified to meet, the agency’s needs.

3. As required by FAR 13.106-3(b)(3)(i), this memorandum explains the absence of competition for this acquisition, as only one source will be solicited for this requirement (or for a portion of the requirement) and the requirement is not expected to exceed the simplified acquisition threshold.

4. This memorandum is derived from Enclosure 3, Department of Navy Simplified Acquisition Procedures Guide (April 2018) and is only applicable to acquisitions under the SAT.

II. DESCRIPTION OF ITEM OR SERVICE (include manufacture/sole source name and address) GridPro is a pre-processing mesh generation software with the ability to generate high quality, block-to-block hexahedral meshes for use in computational modeling of surface ship hydrodynamics.

NSWCCD Computational Fluid Dynamics Division Code 8700 requires one (1) perpetual, floating license for GridPro/Model 1000 (v9) grid generation tool.

III. BASIS FOR DETERMINATION FOR USE OF OTHER THAN FULL & OPEN COMPETITION

Code 871's core technical competency is computational simulations of submarine and surface ship hydrodynamics. Mesh generation is a primary driver of both labor costs and time-to-solution for hydrodynamics simulations. GridPro is a software package that allows for automated generation of high-quality hexahedral

NSWCCD Sole Source/Brand Name Justification Under SAT Rev 4 Template Page 2 of 4 meshes. Hexahedral meshes have numerical advantages over tetrahedral or polyhedral alternatives including lower numerical dissipation and increased control over mesh cell size stretching rates. These numerical advantages translate into increased accuracy in the data that Code 871 delivers to our sponsors.

The features of GridPro's software that set it apart from other hexahedral grid generators are 1) Grid topology definition independent of hull surface geometry, 2) Algorithmic grid smoothing that includes far-field domain boundaries, and 3) Automatic generation of multiple levels of grid refinement. These features translate into Code 871 delivering results to our technical sponsors faster and at lower cost.

GridPro was identified as an ideal software for this specific application under an FY24 COLLECT project, which performed an assessment of eight (8) mesh generation tools. Engineers at NSWCCD tested each candidate meshing tool against five (5) canonical hull designs to determine where each tool excelled or failed in several categories including: versatility, accuracy, speed, and compatibility with multiple CFD solvers. GridPro emerged as the primary tool for surface ship applications.

☐ A. BRAND NAME:

Item required must be a brand name product, or feature of a product, particular to one manufacturer.

☐ 1. Restrictive Rights: The source has established proprietary rights, limited rights in data, patent rights, copyrights, or secret processes in the item or service required.

☐ 2. Exclusive Licensing Agreements: The item or service is only available from the Original Equipment

Manufacturer (OEM).

☐ 3. Other Reasons:

☒ B. SOLE SOURCE (select all that apply)

☒ 1. Restrictive Rights: The source has established proprietary rights, limited rights in data, patent rights, copyrights, or secret processes in the item or service required.

GridPro software is used to generate three-dimensional body fitted meshes for Computational Fluid Dynamic (CFD) simulations. MAKO, developed by NSWCCD Code 871, requires specific meshing characteristics and quality to accurately predict the hydrodynamic interactions between the ocean surface and a forward moving ship hull, NSWCCD Sole Source/Brand Name Justification Under SAT Rev 4 Template Page 3 of 4 as well as accurate predictions of drag, ship trim, and Kelvin wakes. The detailed hydrodynamic characteristics obtained by MAKO are used to provide assessments of ship performance and the influence of design decisions.

Based on an extensive technical study performed under the COLLECT FY24 program portfolio, no other commercial software is compatible with GridPro. Acquisition and implementation of an alternative set of software tools would not be cost effective and feasible. As with any software company, GridPro owns all proprietary rights to its software and does not has any authorized reseller. GridPro is the only distributor of the product. Only GridPro can provide the GridPro software license, subscription, and maintenance renewal due to proprietary rights. Therefore, in accordance with FAR 13.106-1(b)(1)(i) the circumstances of this contract action deems only one source to be reasonably available.

☐ 2. Exclusive Licensing Agreements: The item or service is only available from the Original Equipment

Manufacturer (OEM), or there is only one authorized distributor or technical representative for the OEM. ☐ 3.

Other Reasons:

☐ C. LIMITED SOURCE (FAR 8.405-6):

Item required must be a brand name product, or feature of a product, particular to one manufacturer.

☐ 1. Restrictive Rights: The source has established proprietary rights, limited rights in data, patent rights, copyrights, or secret processes in the item or service required.

☐ 2. Exclusive Licensing Agreements: The item or service is only available from the Original Equipment

Manufacturer (OEM).

☐ 3. Other Reasons:
