Development of a Double Flux Model in the Loci/STREAM CFD Tool

NASA's Shared Services Center (NSSC) has issued a Special Notice regarding the development of a Double Flux Model in the Loci/STREAM CFD Tool. This procurement is designated as a Total Small Business set-aside and falls under NAICS code 541690 for Other Scientific and Technical Consulting Services. The work will be performed at NASA's Marshall Space Flight Center (MSFC) and involves commercial items and services acquired under FAR Parts 12 and 13. NASA intends to award this contract as a sole source procurement to STREAMLINE NUMERICS, INC, located in Gainesville, Florida, under the authority of FAR 13.106-1(b)(1)(i). The agency has determined that STREAMLINE NUMERICS, INC is the sole provider capable of developing this specialized CFD tool enhancement.

The primary purpose of this Special Notice is to announce NASA's intent to proceed with a sole source contract while providing an opportunity for other qualified organizations to demonstrate their capabilities. Interested contractors must submit written capabilities and qualifications by 4:00 p.m. Central Standard Time on July 15, 2025, just five days after the notice was posted. These submissions will be evaluated solely to determine whether the procurement should be conducted on a competitive basis rather than sole source. The government reserves full discretion in deciding whether to maintain the sole source approach based on received responses. Oral communications are not acceptable, and all submissions must be in writing to the designated points of contact. Organizations responding must demonstrate their ability to perform scientific and technical consulting services related to computational fluid dynamics tool development.
