Automated Grid Deformation Module Development

The contract calls for the development of automated software routines capable of deforming computational fluid dynamics grids in real time to match dynamic changes in aerospike nozzle geometry, ensuring accurate simulation fidelity as design parameters shift. This module must be fully integrated with the Loci/CHEM framework, a high-performance simulation platform used for advanced propulsion modeling, requiring seamless data exchange, compatibility with existing solver architectures, and robust handling of complex mesh topologies under extreme deformation conditions. The work targets a specific performance location at Stennis Space Center with a zip code of 39529, where the software will be validated against experimental and simulation benchmarks. The project is structured as a subcontract under NASA’s Shared Services Center, falling under the NAICS code 541715 for scientific research and development services. The solicitation was posted on July 28, 2026, with a strict response deadline of July 30, 2026, indicating a rapid procurement timeline typical of time-sensitive aerospace innovation efforts. While no set-aside provisions or point of contact details are provided, the contract’s focus on grid deformation in propulsion systems underscores its critical role in enabling efficient, high-fidelity analysis of next-generation rocket engines, particularly those utilizing aerospike nozzle configurations to enhance performance across altitude ranges.
